Description
Energies and intensities of more than 192 gamma-transitions were accurately measured, 63 of these are reported for the first time. The 237Np level scheme built on the basis of good sum relationship accounts for 165 γ-transitions de-exciting 46 excited levels; 6 are proposed for the first time: at 712.7, 759.4, 945.3, 962.3, 1015.2 and 1114.3 keV. Spin and parities of the new states were discussed in the framework of the Nilsson's model. (author)
