摘要：

The fractional hyperfine pressure shift (known as HPS in the literature) of paramagnetic atoms in an atmosphere of noble-gas atoms has been found to be computable vertical bar quite adequately from recently evaluated extended-basis-set self-consistent-field molecular-orbital wave functions. The actual computation was carried out for lithium and sodium atoms in a helium buffer gas. Computed values of 78. 87 x 10(-9)/mm Hg versus the experimental value of 77.7 x 10(-9)/mm Hg for LtHe and 78. 11 versus 73. 0 x 10(-9)/mm Hg for NaHe were obtained.
