Title: Modulational Instability of Nonlinear Waves in a Cold Quark–Gluon Plasma
Abstract: We report on the variation in the 64 Ge(p, γ) 65 As reaction rates due to uncertainties of either nuclear mass and level structure of the 65 As isotope or non-resonant reaction rates.The change in the reaction rates is from a few factors to one order of magnitude due to the uncertainty of the nonresonant rates, which were calculated using the astrophysical S-factor and the statistical Hauser-Feshbach model.The mass uncertainty of the 65 As nucleus (∆m = 85 keV) results in a variation of a few factors in the reaction rates at T 9 = 1.At present, the estimated effective lifetimes of 64 Ge in the rp-process are ranging from 0.5 to 162 ms.The results indicate that the resonance at E x = 1.155MeV and the Q-value of the reaction must be precisely determined to improve the accuracy of rp-process simulations.
