“…The only other published work on this cross section was performed by Henkel and Barschall. 40 When their result at 1 MeV is renormalized to newer B (n,a) cross-section results, as suggested by Johnsrud et al? h and to the 42-b thermal cross section, the resulting value is considerably below the other results and is not shown in Fig. 6.…”

Systematic study of neutron capture including the compound, pre-equilibrium, and direct mechanisms

“…Experimental data are taken from Refs. [34][35][36] for 27 Al(n,γ ) 28 Al, [34,37] for 37 Cl(n,γ ) 38 Cl, [13] for 48 Ca(n,γ ) 49 Ca, [38] for 61 Ni(n,γ ) 62 Ni, [39,40] for 97 Mo(n,γ ) 98 Mo, [41,42] for 122 Sn(n,γ ) 123 Sn, [43][44][45] for 176 Lu(n,γ ) 177 Lu, [46,47] for 208 Pb(n,γ ) 209 Pb, and [48][49][50][51][52] for 232 Th(n,γ ) 233 Th.…”

The Total Neutron Cross Sections of Gold, Chlorine, and Phosphorus

“…The average value agrees well with that reported by Adair. 1 The authors wish to acknowledge the continued interest of W. F. G. Swann, Director of the Bartol Research Foundation, in this work.…”

“…1. Hence, it was felt that the correction which is due to the scattering of neutrons into the detector is adequately accounted for by the following formula: (1) where <r is the total cross section, n is the number of scattering nuclei/cm 3 , d is the thickness of the scatterer, N is the counting rate with the scatterer in place corrected for the paraffin shadow cone background, No is the counting rate without the scatterer corrected for the shadow cone background, / is a geometrical measure of the scattering-in correction and is given by…”

“…The effect of the carbon was subsequently subtracted using the carbon cross section given by Adair. 1 Indications of resonances occur at several neutron energies and are separated by about 100 kev.…”
