Frequently Asked Questions (FAQs): NSF Discretionary Grant Opportunity - Nuclear Physics (PD 08-1232)

What is this grant opportunity?

This is a National Science Foundation (NSF) discretionary grant opportunity titled "Nuclear Physics" with Funding Opportunity Number PD 08-1232. It supports basic research at the leading edge of nuclear science and closely related areas of fundamental physics.

What is the main purpose of the program?

The program aims to fund frontier research that improves understanding of the properties, structure, and behavior of atomic nuclei and nuclear matter, especially under extreme conditions of density, temperature, and isospin that are difficult or impossible to reproduce outside specialized experimental environments.

What major scientific themes does the program emphasize?

The opportunity highlights several central themes, including:

• How nuclear matter is built from underlying quark and gluon degrees of freedom
• How nuclear matter changes phase as conditions move from ordinary nuclear densities and temperatures toward the ultra-hot regime where quark-gluon plasma is predicted
• Basic interactions and fundamental symmetries, using nuclear systems as sensitive laboratories for testing the Standard Model and searching for small effects that could indicate new physics

What kinds of research topics are considered within scope?

The scope is broad and includes both experimental and theoretical work. Topics mentioned include nuclear structure and reactions, nuclear matter under extreme conditions, connections to quantum chromodynamics (QCD), phase transitions to quark-gluon plasma, and studies of fundamental symmetries and interactions using nuclear systems.

Does the program include research connected to astrophysics?

Yes. The opportunity explicitly includes investigations connected to astrophysical phenomena, such as nuclear processes governing stellar evolution, supernovae, and the behavior of matter in neutron stars, including conditions involving extreme densities and neutron-rich environments.

What is meant by "quark-gluon basis of nuclear structure and dynamics" in this context?

It refers to research that connects observable nuclear behavior to the underlying theory of the strong interaction (QCD). This includes studies of how confinement, correlations, and collective effects emerge in many-body nuclear systems and how these microscopic degrees of freedom shape nuclear structure and dynamics.

Is research on quark-gluon plasma and phase transitions supported?

Yes. The program emphasizes phase transitions of nuclear matter from "normal" conditions to the predicted high-temperature quark-gluon plasma, including physics commonly explored through high-energy heavy-ion collisions and related theoretical modeling.

What experimental approaches and beam types are included?

The solicitation describes a wide range of experimental venues, including:

• Low-energy through multi-GeV electrons and photons
• Intermediate-energy light-ion beams
• Heavy-ion beams ranging from low-energy to relativistic energies
• Radioactive beams (for short-lived isotopes and neutron-rich nuclei)

Does the program support radioactive beam research?

Yes. Radioactive beams are explicitly highlighted as important because they enable experiments on short-lived isotopes and neutron-rich nuclei that are central to modern nuclear structure research and nucleosynthesis questions.

Are non-accelerator experiments eligible under this program?

Yes. In addition to accelerator-based work, the solicitation recognizes cold and ultra-cold neutron experiments used to test fundamental symmetries and measure precision observables, as well as other non-accelerator-based experiments relevant to nuclear physics and fundamental interactions.

Does the program fund university user groups that use external laboratories?

Yes. A notable feature is support for university user groups that carry out experiments at many laboratories, both within the United States and internationally. This indicates the program can fund teams that rely on shared national and international infrastructure rather than being tied to a single facility.

Are specific user facilities mentioned as part of the program?

Yes. The program explicitly identifies user-facility support including the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University, described as a superconducting heavy-ion cyclotron facility.

Does the program support smaller accelerator laboratories?

Yes. Beyond large facilities, the solicitation notes support for smaller accelerator laboratories, with examples such as Florida State University and the University of Notre Dame. This suggests an interest in a diverse research ecosystem that includes campus-based accelerators and specialized local capabilities.

What type of award is this?

It is categorized as a grant and is listed in the science and technology/research and development activity area.

What is the CFDA number associated with this opportunity?

The opportunity is associated with CFDA number 47.049 (Mathematical and Physical Sciences).

Who is eligible to apply?

Eligibility is listed as unrestricted, meaning a broad range of applicant organizations may apply, subject to any additional eligibility clarifications in the full NSF program text.

Is cost sharing or matching required?

No. The notice indicates there is no cost sharing or matching requirement.

When was this opportunity originally posted?

The posting information lists an original posted date of March 23, 2009.

What are the proposal due dates or target dates?

The solicitation follows an annual proposal target date pattern tied to the last Wednesday in September. Examples listed include September 30, 2009 and September 29, 2010.

Are the number of expected awards or total funding levels provided?

In the provided record, several funding fields (including expected awards and estimated total funding) are shown as 0. This often indicates the amounts were not specified in the summary entry and would typically be clarified in the full NSF program description or annual budget context, rather than implying that no awards will be made.

Where can applicants find the official additional information for this opportunity?

The announcement points to an NSF program description (08-1232) as the additional information link. Details and any clarifications would be found in that program description.

Where should applicants go for technical help accessing the application portal?

The notice provides grants.gov support contact guidance for access issues. For technical access problems, applicants are directed to use the grants.gov support resources referenced in the announcement.

What kinds of outcomes or impacts is the program generally trying to enable?

Based on the solicitation summary, the program is designed to advance fundamental understanding of matter, forces, and symmetries through research on nuclei and nuclear matter, including conditions relevant to extreme astrophysical environments and high-temperature phases like quark-gluon plasma, and through precision studies that can test the Standard Model and probe for new physics.
