Аннотация:The b3PI(u)-A1SIGMA(u)+ interaction in Na2 as manifested by A1SIGMA(u)+ state Lande factors was investigated. Lande factors g(A) were measured from the dispersion shape Hanle signal in fluorescence excited by 647.1 and 676.4 nm Kr+-laser lines. The partial contribution g(Ab) due to weak A approximately b interaction was extracted from measured g factors for v(A), J levels with v(A) between 8 and 29. The electronic part of the spin-orbit (SO) interaction matrix element H(so)e = 5.86 +/- 0.20 cm-1 was determined by deperturbation fitting of g(Ab) values. Possible error sources in A1SIGMA(u)+ state g-factor treatment due to imperfection in the physical model employed, inaccuracy of existing set of b3PI(u) state molecular constants and nonlinear magnetic field effects were analyzed.
