Investigates experimentally the broadening and the shift of the sodium 3S-4D and 3S-5S two-photon transitions without Doppler broadening by collisions with the noble gases. The broadening cross section is larger for the 3S-5S transition than for the 3S-4D transition. The experimental values for the 3S-5S transition are compared with semiclassical calculations using the van der Waals potential and the potentials calculated by Pascale and Vandeplanque (1974).
