High Accuracy Calculation for Excited-State Energies of H Atoms in a Magnetic Field

摘要

Using the recently developed finite-basis-set method with B splines,excited states of H atoms in a magneticfield have been calculated.Energy levels are presented for the ten excited states,2s_0,3d′_0,3p_0,3d_(-1),3d_(-1),4d_(-1),3d_(-2),4d_(-2),4f_(-2),and 5f_(-2) as a function of magnetic field strengths with a range from zero up to 2.35 × 10~6 T.The obtainedresults are compared with available high accuracy theoretical data reported in the literature and found to be in excellentagreement.The comparison also shows that the current method can produce energy levels with an accuracy higher thanthe existing high accuracy method [Phys.Rev.A 54 (1996) 287].Here high accuracy energy levels are for the first timereported for the 3d′_0,4d_(-1),4d_(-2),4f_(-2),and 5f_(-2) states.
