强磁场下的氦-4原子
Helium-4 atom in strong magnetic fields
采用基于Hylleraas-Gaussian基的组态相互作用方法，本文计算了外磁场下氦原子的基态和低激发态非相对论能量。零场时,基态能量提高到-2.9037235,精度的提高使计算中考虑有限核质量成为可能。本文进一步计算了外磁场下氦-4原子的基态和低激发态非相对论能量，计算的磁场强度区间为0-10原子单位（1原子单位为2.35*10^5特斯拉）。
Using the configuration-interaction method based on the Hylleraas-Gaussian basis sets, the non-relativistic ground state energy of helium atom in zero magnetic field is improved to -2.9037235, which make it possible to take a full consideration of the effect of the finite nuclear mass. In this study, we investigate the energy levels of the ground state and some lower excited states states of the helium-4 atom in magnetic fields up to 10a.u. (1a.u. corresponding to 2.35*10^5T).
