Popis:	Dispersed laser induced fluorescence, and time domain measurements using the optical Kerr effect are applied to study the relaxation dynamics of Xe+F− (B 2Σ1/2 and C 2Π3/2) charge transfer states in solid Ar. Very fast vibrational relaxation is observed in the C emitting site: excitation near v=20 leads to population of v=0 of the C state in 13(±2) ps. In the B emitting site, the lower vibrational states relax sequentially. Relaxation times of 800(±30) ps for 1→0 and 250(±30) ps for 2→1, are measured directly; and 150(±30) ps for 3→2 and
