K- to L-shell vacancy transfer probabilities were measured for ten elements in the atomic range 73 less than or equal to Z less than or equal to 92. Those measuring L x-ray yields from targets excited by 59.5 and 122 keV incident photons, i.e., below and above the K edge of elements, were detected with a high-resolution Si(Li) detector. For comparison with experimental results, theoretical calculations were made by using available data on radiative and radiationless transitions. The radiative transitions of these elements were observed from the relativistic Hartree-Slater model which was proposed by Scofield [At. Data Nucl. Data Tables 14, 121 (1974)]. The radiationless transitions were observed from the Dirac-Hartree-Slater model which was proposed by Chen, Craseman, and Mark [At. Data Nucl. Data Tables 24, 13 (1979)] The measured results were found to be in good agreement with theoretically calculated values. The experimental and theoretical values were fitted versus atomic number Z.
