Abstract:

Performing quantitative calculations of nuclear observables is a guiding principle of nuclear theory. In general, we are concerned with computing physical quantities that can be, at least in principle, experimentally measured. The spectra of nuclear systems is the most common, and easiest, observable to calculate.  However, computing other observables such as the root mean square (RMS) radius, strengths of various transitions, reaction cross sections, etc. is also of great interest. This proposal outlines two different, but closely related, projects that investigate various nuclear observables in two different frameworks: (1) Within an ab initio no-core shell model to investigate external operators in light nuclei and (2) using phenomenological interactions to investigate the systematics of transitions for excited states in larger nuclei.  To achieve these goals I will develop tools to be used in combination with currently available many-body solvers. These solvers perform two major tasks: They compute the nucleon-nucleon or three-nucleon interaction and/or read in a previously computed interaction and they compute spectra and wavefunctions for the chosen nuclear system. I will create new codes and modify the existing solvers to calculate and handle the chosen operators. In addition, when calculating observables for light nuclei, I must soften the chosen interactions.
