Abstract

Two approaches to the analysis of level crossing are presented. A theoretical approach utilizes values of the hyperfine coupling constants to predict the entire level structure of a system, including all level-crossing data of interest. A second approach suggests a procedure for determining hyperfine parameters with reasonable accuracy, based on three or four measured quantities. Results of this procedure in 2 P2 lithium give the contact, dipole, and orbital hyperfine coupling constants as -9.806 0.117, -1.909 0.034, and 8.638 0.39 MHz, respectively. This work reemphasizes the fact that an accurate determination of magnetic hfs requires three parameters to fully define the three independent magnetic hyperfine interactions. © 1970 The American Physical Society.
