Physical Review a
We report the results of a study of the pressure broadening and resonant frequency shift of the absorption profiles of the D-1 and D-2 lines of Rb and K in the presence of He-3 and N-2 gases over a range of number densities. We have also examined the temperature dependence of the broadening and shift over a range of approximately 340 to 400 K. We compare our results for the broadening and shift coefficients for Rb D-1 and D-2 to current values and present coefficients for K D-1 and D-2. DOI:10.1103/PhysRevA.87.032516
