Abstract.A stimulated resonance emission and stimulated Raman scattering signals have been generated in an atomic sodium and rare gas mixture by a laser tuned to the 32 Sin-32 P3/2 transition. The intensity dependence of these effects on the buffer gas pressures is obtained in the experiment. We demonstrate good qualitative agreement between experimental observations and a simple theoretical model. A new method using stimulated emission is applied to measure the cross section for the J mixing of 3P states of sodium due to collisions with noble gas atoms. Good agreement between our results and the measurements of Pitre and Krause is obtained for Ar and Kr perturbers PACS: 32.80.Wr; 32.90. +a
