Description of the thesis topic
The goal of the thesis is to provide a deep theoretical study of the nuclear reactions rates important for astrophysics. The method of choice is the configuration-interaction approach. A specific attention will be paid on the isospin-symmetry breaking effects and the so-called Thomas-Ehrman shift. The results will be of importance for astrophysical simulations.
Analytical and numerical theoretical developments, calculations of nuclear properties in the framework of the nuclear shell model, creation of new effective interactions which break of the isospin symmetry, calculations of nuclear reaction rates, participation in the astrophysical simulations of the X-ray bursts and/or novae outbursts (depending on the candidate's interests).
Radiative proton capture reactions in stars play an important role in the hydrogen burning in type I X-ray bursts (rp process) or novae outbursts. Numerous reactions have not been measured yet experimentally and thus theoretical estimations are required. Previous calculations were often based on various approximations.
