【摘要】 采用发展的(Finite-basis-size)方法用(B-splines)基在典型的磁化白矮星强磁场中计算了类氢离子He~+的离散光谱。涉及到的磁场范围为2.35～2 350 MG。计算共涉及9个磁化原子态，包含3种对称性0~+、0~-和(-1)~+,计算了8种电偶极跃迁的波长、振子强度和跃迁速率。此8种电偶极跃迁分别为1 0~+→ν 0~-(ν=1-4)和1 0~+→ν(-1)~+(ν=1-4)。计算结果显示此8种电偶极跃迁的波长均分布在紫外区域，当磁感应强度γ=0.2a.u时1 0~+→4 (-1)~+跃迁属于弱跃迁。计算结果可作为天体物理的参考数据。更多还原

【Abstract】 By using the recently developed finite-basis-set method with B-splines, the discrete spectra of hydrogen-like ion He~+ have been calculated in a strong magnetic field typical of magnetic white dwarf stars.The magnetic field strengths involved ranged from 2.350 to 2 350 MG. The calculation involves a total of 9 magnetized atomic states with the symmetries 0~+,0~- and(-1)~+.The wavelengths, oscillator strengths and transition probabilities for eight the electric dipole transitions relevant to these magnetized atomic states are reported.The eight electric dipole transitions are 1 0~+ → ν 0~-(ν=1-4) and 1 0~+ → ν(-1)~+(ν=1-4),respectively. The calculated results show that the wavelengths of these eight electric dipole transitions are all distributed in the ultraviolet region and the transition 1 0~+ → 4(-1)~+ at γ = 0.2 au belong to weak transition.The results of this calculation can be employed as a reference data for astrophysics.更多还原
