Abstract
The total transition probabilityf 23 for theL 2-L 3 Coster-Kronig transition probability atZ=80, 81, 82, and 92 was measured withL α x-ray coincidences between high resolution Si(Li) and Ge(HP) x-ray detectors and a dual-parameter multichannel coincidence system. TheL α gating technique for observing theK x-ray coincidence spectrum was carefully checked and found to be equivalent to the method of observing theL x-ray spectrum with\(K_{\alpha _{1,2} } \) gates, when proper corrections are applied. The values off 23 found are 0.123±0.012, 0.109±0.011, 0.105±0.011, and 0.146±0.018 atZ=80, 81, 82, and 92, respectively. These values, together with all previously published values in the region 57≦Z≦96, are critically evaluated and a group of “best values” selected for comparison with theory. The agreement is quite good in the region 63≦Z≦83. The independentparticle model employing a Green-Sellin-Zachor potential used by Chen and Crasemann predicts values off 23 which are too large compared with experiment in the high-Z region, whereas the theoretical predictions of McGuire using an approximate Herman-Skilman potential are too low. However, the screened nonrelativistic hydrogenic results of Chen, Crasemann, and Kostroun are in satisfactory agreement with the experiments. The experimental result atZ=92 indicates that theL 2-L 3 M 4 transition is at or below threshold and contributes little or no intensity to the value of f23.
