Hyperfine structure in the 2P2 state of atomic lithium

Abstract

Calculations by two different theoretical methods are in good agreement with each other and with available experimental data on hyperfine splitting and Zeeman level crossing of 2P2 lithium. These results show unequivocally that the contact, spin-dipolar, and orbital hyperfine interactions must be described by three independent parameters. © 1970 The American Physical Society.
