L Shell Fluorescence Yields and Coster-Kronig Transition Probabilities Using Radioactive Sources.
Abstract
Accurate knowledge of x-ray fluorescence yields is an important ingredient in the solution of many practical problems and in the understanding of the decay mechanisms of atomic states characterized by inner-shell vacancies. In the present work, coincidence and singles techniques, employing high resolution semiconductor x-ray detectors and radioactive isotopes, are applied to obtain information on the decay of inner-shell vacancy atomic states. Precision measurements of K-shell fluorescence yields at Z = 78, 82 and 92 are performed. X ray and Coster-Kronig yields at Z > 60 are measured. It is clearly established that a discrepancy exists in the interpretation of experimentally observed L2 subshell Coster-Kronig transition probability around Z = 80. A careful and detailed study of the decay of (LL)-, (LX)-vacancy atomic states at Z = 82 (in the decay of 207 Bi) is made by (x-ray)-(x-ray) and (x-ray) Auger electron coincidence techniques.
