Abstract
The 59.5-keV γ-ray emission rate of 241Am sources has been measured with a windowless 4 π-CsI(T1)-sandwich spectrometer. Photon attenuation by the α-particle absorbers was minimized by an optimal shape of these absorbers. The disintegration rates of the same 241Am sources were obtained by α-particle counting under defined low solid angles. The ratio of the two measured quantities, the 59.5-keV γ-ray emission probability, was found to be 0.3636 ± 0.0017 which is slightly higher than the recommended value of 0.359 ± 0.004.
