Description

The FRIB-TA Topical Program: Optical Potentials in Nuclear Physics will be held at the Facility for Rare Isotope Beams (FRIB) on the campus of Michigan State University (MSU) in East Lansing, MI USA.

Goal of Program

Optical potentials play a central role in the theoretical description of processes like, e.g., direct nuclear reactions and neutron capture rates. Direct reactions, such as nucleon transfer, knockout, inelastic excitation, etc., have been at the basis of our understanding of nuclear structure since the advent of the first particle accelerators, and will continue to be at the center of FRIB activities. 

In order to fully exploit the information obtained from FRIB experimental results since its first day of operation, it is pressing to foster the development of reliable optical potentials to be used far from nuclear stability, beyond the reach of current standard implementations and to quantify the theoretical uncertainty associated to optical potentials.

 The goal of the present program is to:

  • Review the existing strategies to derive optical potentials, and the underlying associated structure theory approaches.
  • Assess the reliability and ranges of validity of the different approaches, as a function of beam energies and mass numbers. 
  • Make recommendations concerning the future developments, and provide a road map both for the derivation of the new generation of optical potentials and the associated uncertainty quantification.

The Topical Program is organized by the FRIB Theory Alliance. For selected participants we hope to provide partial support which may include lodging and meals. After registration has closed you will be contacted with the support we are able to provide. We will not provide support for transportation expenses.
