Sažetak
The differential cross-section dsigma/dE/dOmega was measured at an incident photon energy of 105.3 keV in germanium on absolute scale. The measurements were made using two high-purity Ge detectors that operataed in a coincidence mode. One detector served as the target and detector of ejected electrons, and another as the detector of Compton-scattered photons. It was found that fast (multiple) cascades have little influence on the data of the 105.3 keV crossover transition. An improved determination of the detector efficiency was made. The calculated values of the cross-section dsigma/dE/dOmega using the impulse approximation (IA) with Hartree-Fock wave functions are in excellent agreement with the experimental cross-sections, while the IA with hydroge-like (HL) wave functions gives a fair agreement. A comparison of the calculated values of the cross-sections obtained with HF and HL wave functions for each subshell in germanium gives new values for effective charges, which improve agreement between results od IA with HL and experimental values.
