Abstract

The radiative lifetimes of the levels of the Kr ii 5p configuration have been measured by a transient-decay technique. Excitation is obtained with threshold-energy electrons. Decay rates were measured over the range of gas pressures, 0.02 to 1.0 torr, indicating a de-excitation cross section for collisions with the krypton background gas of ~ 10⁻¹⁴ cm² at 385°C. Lifetimes of the unperturbed 5p levels range from 7.7 to 10.2 ns; for the unperturbed 5p′ levels the range is 6.0 to 8.9 ns. The error in the measured lifetimes is estimated to be less than 5%. The lifetimes are generally found to agree with intermediate-coupling calculations within 20%. They are also compared with recent beam-foil measurements.
