Collision-induced dipole transitions and collisional broadening in the wing of Cs(5D) due to mixing with Cs(7S) and Cs(6P) are studied using two-photon resonance ionization spectroscopy. From the structure of the line shape, we measured the van der Waals well of the ground state without performing a temperature study or using the calculated potential curves, and from the absolute yield we measured the induced-dipole oscillator strength as a function of the internuclear separations at large separations. The results are compared with theoretical calculations.
