“…Similar to the approach by Mather et al, Frehaut et al [15] used a large gadolinium-loaded liquid scintillator to determine the 238 U(n,2n) 237 U cross section. In recent years, Naik and his group [23][24][25][26] used the activation technique for the cross-section measurements at E n = 8.0, 10.0, 12.0, 14.8, and 15.5 MeV. Our present data are in good agreement with the values reported by Knight et al [6] and Raics [16].…”

Measurement of fission product yields in the quasi-mono-energetic neutron-induced fission of 238U

“…The neutron beam was obtained from the 7 Li(p, n) 7 Be reaction by using the proton beam from the 14UD BARC-TIFR Pelletron facility at Mumbai, India [71][72][73]. The main proton beam line at 6 m height above the analyzing magnet of the Pelletron facility was utilized to have a maximum proton current from the accelerator.…”

Neutron spectra produced by 30, 35 and 40 MeV proton beams at KIRAMS MC-50 cyclotron with a thick beryllium target

“…After completion of the irradiation period, the induced gamma-ray activity in the sample is measured by a gamma-ray detector for a period T CL . For the gamma-ray of a given energy in the recorded spectrum, the net area of the full energy photo-peak ðA net Þ at T ¼ T IR þ T CO þT CL is given by the following expression [39]:…”
