Study of some nuclear parameters in the decay of 131Ba

The sum peak method has been applied to calculate K-electron capture probabilities to 216, 373, 585, 620 and 1048 keV levels of 131Cs. The relative and absolute intensities of γ-rays have been calculated using a high-resolution HPGe detector. K-conversion coefficients of 123 and 133 keV transitions have been calculated using summing phenomena.
