Internal conversion electrons from 147Nb decay

To obtain independent data about the multipolarities of γ-transitions in 147Pm the investigations of the spectrum of the electrons of internal conversion is studied. The measurements were taken on the prismatic beta spectrometer at the resolution 0.1-0.2% per impulse. Besides measurements of γ-spectrum, spectrum, of γγ-coincidences and investigations of angle γγ-correlations with the use of Ge(Li) detector with the aim of specifying quantum characteristics of 147Pm levels were carried out. The scheme of 147Pm levels is presented
