Measurement of the yield of fission products of235U and239Pu by the method of semiconductor gamma spectrometry

Determination of 238U(n, γ) and 238U(n, f) reactions cross-section in the neutron emission spectrum of 241Am-Be source

“…There were few data concerning 238 U(n, f) 134 I and 235 U(n, f) 134 I which are related to the decay to 134 Te as an accumulative mass range. In figure 9(a), data were taken from [55,61] are related to 134 Te accumulative mass range, not to the specific yield of 134 I; hence, they were disregarded from our polynomial fitting. Only data from [60] are Table 2.…”

“…Figure 6 illustrates the variation of the fission yield of143 Ce with neutron energy for 235 U(n, f) reaction (denoted Y 5 ) and for 238 U(n, f) reaction (denoted Y 8 ). Data points for 143 Ce in 235 U(n, f) reaction are from[43][44][45][46][47][48][49][50][51][52][53][54][55]. Data points for 238 U(n, f) reaction are from[47,48,50,51,[56][57][58][59].…”

“…Typically, Y 8 = 4.2 ± 0.3% while Y 5 = 5.1 ± 0.4%. In figure12, data for 238 U(n, f) 92 Sr were taken from[47,50,[56][57][58][59] while data for 235 U(n, f) 92 Sr were taken from[44,47,48,50,52,55].…”
