摘要：

Radiative lifetimes of AIH(AID) A 1Π have been measured in a hollow cathode discharge by dye laser excitation, in ns: AIH{ v′ = 1: 83 ± 6v′ = 0: 66± 4 AID{v′ = 1: 74 ± 5v′ = 0: 64± 5 Predissociated rotational levels lifetimes are given and used to precise the shape of the hill of the A 1Π potential energy curve crossed by tunnel effect. The AIH dissociation energies are found: for A 1Π, De(eV) = 0.24±0.01 and for X 1Σ+, De(eV) = 3.16±0.01. The normal levels lifetimes variation with v′ is attributed to a configuration mixing in A 1Π. © 1979 American Institute of Physics.
