Popis:	Collisional quenching of In(5p2 4P1/2) and In(6p 2P) by Ar, H2, D2, N2, and CH4 has been measured by laser pumping of the 5p2 4P1/2 level. The quenching cross sections for 5p2 4P1/2 range from 1.6×10−16 cm2 for Ar to 37×10−16 cm2 for H2. The cross sections for quenching the 6p 2P state range from 0.96×10−16 cm2 for Ar to 18×10−16 cm2 for H2. The radiative lifetimes of the 5p2 4P1/2 and 6p 2P state were found to be 950 and 104 ns. Population ratios measured under steady‐state conditions show that much of the excited‐state population resides in the 6s 2S1/2 level after excitation of the 5p2 4P1/2 or 5d 2D levels.
