强磁场对非零温中子星壳层电子俘获反应的影响

本文讨论了强磁场作用下非零温电子气体的化学势，分析了磁场作用下电子气体屏蔽势的变化；以核素３３Ｓ为例，讨论了不同温度下，磁场对电子俘获率的影响，结果表明：在足够低的温度和密度下，足够强的磁场使电子俘获率显著降低，而就中子星表面存在的磁场强度（１０９－１０１３Ｇ）而言，磁场对其电子俘获率几乎没有影响．

INFLUENCE OF STRONG MAGNETIC FIELDS ON ELECTRON CAPTURES IN NON-ZERO TEMPERATURE CRUSTS OF NEUTRON STARS

In this paper the chemical potential of a non-zero tmperature electron gas embedded in a strong magnetic field is discussed and the effect of a magnetic field on the electron screening potential is analyzed. The influence of a magnetic field on the electron capture rate of the nuclide 33S, as an example, at various temperatures is investigated. It is shown that a strong enough magnetic field decreases the capture rate very much at sufficiently low temperatures and densities, but the magnetic fields (109-1013G) on surfaces of neutron stars have almost no effect on the electron electron capture rate.
