Two photon spectroscopy of the 6p manifold of xenon

A computer-controlled, frequency-doubled, tunable pulsed dye laser was used to excite members of the 6p manifold of xenon at pressures from less than one Torr to ten thousand Torr. A sensitive detection scheme, linear over a broad dynamic range, was used to measure the fluorescene from the laser excited and collisionally excited states. The two photon absorption profiles for the three dipole-dipole allowed transitions from the ground state have been recorded. These spectra have been analyzed using the impact approximation, the quasistatic approximation, and the Anderson-Talman theory to extract the interaction potentials of these states with ground state xenon atoms for internuclear separations greater than 3.75 Angstroems
