A study of the relative intensities of the gamma rays from the decay of Ta/sup 182/ to W/sup 182/ was performed using the external conversion method. Photo-electrons from uranium converters are analyzed in a doubhe-focusing beta ray spectrometer. To obtain relative gamma ray intensities, corrections for angular dependence of the photo-electric process are applied according to the method of Huhtberg. Corrections for self-absorption in the source are considered and their importance in the low energy region is emphasized. Special experiments with three sources of different thicknesses are carried out in order to obtain an experimental check for calculated corrections for self-absorption. K conversion coefficients are calculated using relative intensities of the internal conversion lines from other work. The experimentally obtained data are compared with predictions of the unified nuclear model as well as the DavydovFilippov theory for non-axially symmetric, even nuclei. (auth)
