Ab initio calculations of reactions of light nuclei
Abstract
An ab initio (i.e., from first principles) theoretical framework capable of providing a unified description of the structure and lowenergy reaction properties of light nuclei is desirable as a support tool for accurate evaluations of crucial reaction data for nuclear astrophysics, fusionenergy research, and other applications. We present an efficient manybody approach to nuclear bound and scattering states alike, known as the ab initio nocore shell model with continuum. In this approach, squareintegrable energy eigenstates of the Anucleon system are coupled to (AA)+A targetplusprojectile wave functions in the spirit of the resonating group method to obtain an efficient description of the manybody nuclear dynamics both at short and medium distances and at long ranges. We show that predictive results for nucleon and deuterium scattering on ^{4}He nuclei can be obtained from the direct solution of the Schröedinger equation with modern nuclear potentials.
