摘　　要：采用Finite-basi-et方法研究了在核质量为无限大框架下磁化的白矮星磁场范围中H原子下莱曼系的0_和(-1)+=7,8)四个电子态向基态10+跃迁的光谱特性,计算出在0.001、0.01、0.1和10a.•磁感应强度下四种跃迁10+,0_和10+,(-1)+(=7,8)的波长、偶极强度和跃迁速率,同时也给出考虑核质量的计算结果,相关研究成果对磁化的白矮星的分立谱观测提供理论参考。The Finite-basis-size method is adopted to calculate the discrete spectral lines of H atoms in strong magnetic fields with the strengths as 0.001,0.01,0.1 and 1.0 a.u.,which are quite typical of magnetic White Dwarf stars.The presented calculations involve four electronic states as^0 and v(-1)+with v—1 and v=8,and four transitions as 10+—>v 0 and 10+—^v(-1)+(v=7,8)relevant to Lyman-series spectral lines.Wavelengths,dipole strengths and transition probabilities are presented under the infinite proton mass and with the finite proton mass.The results provide theoretical reference for the discrete spectrum observation of magnetized White Dwarf stars.
