摘 要: 本文计算在初生中子星中微子驱动的星风环境中弱电荷屏蔽对质子电子俘获反应的影响.结果表明电荷屏蔽对星风中核子的比加热率、熵等物理参量基本没有影响.但是可以明显提高电子丰度,而这种提高有力地支持了最新的快中子俘获核合成结果. We investigate a weak electron screening effect on the electron capture of proton in the neutrino-driven wind of proto-neutron stars. Our results show that the electron screening has little influence on specific heating rate, entropy and other physical parameters in the wind. However, it improves electron fraction obviously, which strongly supports the latest nucleosynthesis of rapid neutron capture process.
