We derived new thermonuclear 64Ge(p,γ)65As and 65As(p,γ)66Se reaction rates based on recently evaluated proton separation energies Sp and nuclear structure data from large-scale shell model calculation. These two rp processes are sensitive to adequately small change of Sp values, spectroscopic factors of proton captures, and densities of excited states of the final nucleus. The precisely measured and evaluated proton separation energies, Sp(65As) and Sp(66Se), largely influence the rates compared to currently available JINA data sets, REACLIB, particularly about two order for 64Ge(p,γ) rate. By using one-zone post-processing type I X-ray burst model simulating the nucleosynthesis within accreted envelopes of neutron stars in close binary systems, we found that the new rates based on newly evaluated Sp(65As) and Sp(66Se) values, resonant energies, and spectroscopic factors estimated from shell model significantly affects the productions of nuclide in the range of 64 ≤ A ≤ 110 about one to ten times compared to productions of nuclide based on presently available REACLIB data. The astrophysical impact of our new rates will be presented.
