Title: Sequential proton capture reactions in the rp-process

Abstract

Detailed shell shell model calculations have been performed to study the structure of unbound excited states in the neutron deficient T=3/2 and T=2 nuclei in the mass range A=20--30. Excitation energies, single particle structure as well as {gamma} transition strengths were computed. On the basis of these results new reaction rates were calculated for the two proton capture sequences, {sup 22}Mg(p,{gamma}){sup 23}Al(p,{gamma}){sup 24}Si and {sub 26}Si(p,{gamma}){sup 27}P(p,{gamma}){sup 28}S. The consequences of these new rates for the reaction flow and the rp-process nucleosynthesis at different stellar temperature and density conditions will be discussed. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
