Özet

K shell radiative transition probabilities and K, L-2 and L-3 shell/subshell fluorescence yields were measured using the Kbeta/Kalpha intensity ratio for seven elements in the atomic number range 30 less than or equal to Z less than or equal to 40 (Zn, As, Se, Rb, Sr, Y and Zr). The targets were irradiated with gamma photons of energy 59.5 keV from Am-241. The obtained values were compared with the theoretical values. It was observed that the present values agree with previous theoretical results. The L-2 and L-3 subshell fluorescence yields were the first measured for the present elements.
