Land´e factors for even-parity 5pnp and 5pnf J = 1, 2 levels along the Rydberg series of Sn I

Land´e g-factors have been measured by time-resolved laser-induced fluorescence and Zeeman
quantum-beat techniques for the even-parity levels of the J = 1 5pnp (n = 11–13, 15–19) and J
= 2 5pnp (n = 11–13, 15–19, 31, 32), 5pnf (n = 4, 5, 9–19, 22, 23) Rydberg series and for all the 5p7p and 5p8p perturbing levels of neutral tin. A two-colour two-step excitation scheme was used in the experiment. The experimental results have been compared with theoretical g-values obtained by the multichannel quantum defect theory and the relativistic Hartree–Fock theory, respectively. In most cases, the theoretical values agree well with the experimental data.
