Collisional deactivation of the5sand4pstates of Na byN2

Abstract
The collisional deactivation of the Na 5s and 4p states by collisions with N2 molecules has been studied using the method of laser-induced fluorescence. The total cross sections for the depopulation of the 5s and 4p states are 86(8) and 43(4) Å2, respectively. The cross sections for the specific collisional transfers 5s4p, 5s3d, and 4p3d are 32(8), 10(2), and 19(3) Å2, respectively.
