Popis: We present a new set of 64Ge(p, γ)65As and 65As(p, γ)66Se reaction rates based on recently evaluated proton separation energies Sp(65As) and Sp(66Se), and nuclear structure data from large-scale shell model calculations. Our new 64Ge(p,g) rate differs from those available in REACLIB by up to two orders of magnitude at temperatures encountered within type I X-ray bursts. We used one-zone post-processing type-I x-ray burst model to test our new rates, and present the astrophysical impact of these rates.
