Measurement of K to L shell vacancy transfer probabilities for the elements 52⩽ Z⩽68

Abstract

The probabilities for transfer of vacancies from K to L shell were measured using intensity ratio of K α and total L x X-rays. The K α and total L x X-rays yields from the targets excited by 59.5 keV incident photon were obtained using a Si(Li) detector. These experimental results were compared with the theoretically calculated values using radiative and radiationless transitions. The radiative transitions of these elements were observed from the relativistic Hartree–Slater model, which was proposed by Scofield (Atom. Data Nucl. Data Tables 14 (1974) 121). The radiationless transitions were observed from the Dirac–Hartree–Slater model, which was proposed by Chen et al. (Atom. Data Nucl. Data Tables 24 (1979) 13). A fairly good agreement is found between the experimental and calculated values.
