摘要
求解了恒定均匀的强磁场中核子的能谱和波函数,在手征表象中给出含核子反常磁矩(AMM)项的Dirac方程的解;并且计算了中子星内壳层物质的物态方程(EOS)和粒子丰度,发现在强磁场中磁能将使中子星内壳层的压强增加但物质仍然是丰中子,AMM项对质子的极化度有明显效应.
We calculate the energy spectra and eigenfunctions of nucleons in a constant magnetic field. Concrete solutions of the Dirac equation including the anomalous magnetic moment (AMM) of nucleons are provided in the chiral representation. They are then used to investigate the equation of state (EOS) and particle ratios on the inner shell layer of neutron stars. The results show that the magnetic energy of strong field will increase the pressure on the inner shell layer neutron star, but the matter remains to be a neutron-rich matter. It is found that the AMM has evident effects on the proton polarization.
