Measurements of Prompt Neutron Multiplicity Distributions in Correlation with Mass-Energy Distribution of Fission Fragments in Spontaneous Fission of²⁵²Cf,²⁴⁴Cm and²⁴⁸Cm

β -delayed fission of Am230

“…248 Cm is a longlived (T 1/2 = 3.5 × 10 5 yr) isotope with a spontaneous fission branching ratio of b SF = 8.39%. The total kinetic energy release for fission fragments is TKE( 248 Cm) = 182.2 MeV, with the most probable energies for light and heavy mass peaks of 103.4 and 78.7 MeV, respectively [16]. The fission fragments from 248 Cm can pass through GARIS with some probability and be registered in the PSD as single-fold events, producing some of the high-energy events in the region above 20 MeV and up to ∼100 MeV in Fig.…”

Calculation of Neutron Production Rates and Spectra from Compounds of Actinides and Light Elements

“…The parameters of some nuclides are presented in the Tables 2 and 3 in comparison with [17][18][19]. Neutron spectral measurements have been reported [6] for two mixtures, one contains 227 AcO2 with daughter products and the second contains dioxide 244 CmO2 mixed with 13 C powder target material and [7] for 210 Po- 13 C source of neutrons .…”
