The low-energy electron spectrum from the -decay of
The low-energy electron spectrum from the -decay of has been analysed in the region of 2.5-22.5 keV at the 20 eV instrumental resolution using a combined electrostatic spectrometer and a radioactive source prepared by vacuum evaporation. Energies , (?), , , , and have been determined for nuclear transitions in . Relative intensities of some conversion electron lines of these transitions have also been derived. For the 26.3 keV E1 and 43.4 keV transitions, the nuclear structure parameters , and the E2 admixture , respectively, have been obtained. Values of , , and were measured for the dominant , , and Auger transitions in Np, respectively.
