Measurement of K shell radiative transition probabilities and K, L_2 and L_3 shell/subshell fluorescence yields of some elements in theatomic number range 30<=X<=40

摘要

K shell radiative transition probabilities and K, L_2 and L_3 shell/subshell fluorescence yields were measured using the K_#beta#/K_#alpha# intensity ratio for seven elements in the atomic number range 30 <= Z <= 40 (Zn, As, Se, Rb, Sr, Y and Zr). The targets were irradiated with #gamma# photons of energy 59.5 ke V 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.
