“…1). More specifically, only one dataset exists for neutron energies up to 9.5 MeV [2] and a few around 14.5 MeV with large discrepancies among them [3][4][5][6][7]. These datasets are mainly deduced by measuring the α-particles of the 236 Pu decay after chemical separation of Pu from Np and using 239 Pu/ 242 Pu tracers.…”

The cross section measurement of the 237 Np(n,2n) 236 Np reaction has been attempted at an incident neutron energy of 9.5 MeV by means of the activation technique. The neutron beam was produced via the 2 H(d,n) 3 Ηe reaction at the VdG Tandem accelerator of NCSR "Demokritos". It is the second time that this measurement has been tried with a gamma spectroscopy method and the difficulties faced due to the high gamma ray background produced by the sample itself and the fission fragments produced by the irradiation, in combination with the very low intensity of the gamma ray of interest are being reported.

“…Though experimental data are available for 242 Am [10], we will use a simplified approach, since experimental level scheme and γ-decay intensities are still incomplete. Modeling of low-lying levels of 242 Am in [8] is accomplished based on the assumption that ground and first few excited states are of two-quasi-particle nature. For actinides with quadrupole deformations the superposition principle is usually adopted, the bandhead energies of the doubly-odd nucleus are generated by adding to the each unpaired configuration ) , ( n p   , as observed in the isotopic/isotonic (A-1) nucleus, the rotational energy contribution and residual (n−p) interaction energy contribution.…”
