用大尺度壳层模型计算了质量范围A = 45-65的pf -壳层核在恒星环境中的弱相互作用率。计算的捕获率和衰减率考虑了最新的实验能级和对数ft值。这些速率与Fuller， Fowler和Newman在密度ρ Y =10 -10 11 g/ cm3和温度T =10 7 -10 11 K时所使用的密度和温度网格点相同，因此与两种类型的超新星（Ia型和II型）都相关。为了便于在恒星演化编码中使用插值速率，还给出了捕获速率和平均中微子（反中微子）能量的有效< ft >值。
Abstract The weak interaction rates in stellar environments are computed for pf -shell nuclei in the mass range A =45–65 using large-scale shell-model calculations. The calculated capture and decay rates take into consideration the latest experimental energy levels and log ft -values. The rates are tabulated at the same grid points of density and temperature as those used by Fuller, Fowler, and Newman for densities ρ Y e =10–10 11 g/cm 3 and temperatures T =10 7 –10 11 K, and hence are relevant for both types of supernovae (Type Ia and Type II). Effective 〈 ft 〉 values for capture rates and average neutrino (antineutrino) energies are also given to facilitate the use of interpolated rates in stellar evolution codes.
