用伪谱方法计算磁场中的氢原子能谱

Spectrum Calculations of Hydrogen in Magnetic Fields with Pseudospectra l Method

摘要: 介绍了用伪谱方法计算磁场中的氢原子 ,通过对氢原子能级的计算 ,可以看出其精度高 ,收敛快 ,并可用来计算任意强的均匀电场和磁场中的其它原子.We use pseudospectral method in spherical coordinate to cal culate the energy levels of hydrogen in magnetic fields up to 10 4 T. The re sults have high numerical accuracy and fast convergence. This method can be used in calculating other atoms in arbitrary electronic and magnetic fields.
