摘要

We have derived new thermonuclear 64Ge(p, )65As and 65As(p, )66Se reaction rates based on recently evaluatedproton separation energies[1] and large-scale shell model (LSSM) calculation. The precisely measured or evaluatedproton separation energies of Sp(65As) and Sp(66Se), are (90±85) keV and (1720±310) keV, respectively. Weutilized one-zone post-processing type I X-ray burst model[2] to investigate the astrophysical impact of our newrates. We found that the new experimental Sp(65As), resonant energies and spectroscopic factors estimated fromLSSM significantly affects the productions of nuclide in the range of 64≤A≤110 about one to ten times comparedto currently available JINA data sets, REACLIB[3].
