Neutron Activation Cross Sections forBr79,Br81,Rh103,In115,I127, andTa181

Abstract

Neutron activation cross sections for ${\mathrm{Br}}^{79}$, ${\mathrm{Br}}^{81}$, ${\mathrm{Rh}}^{103}$, ${\mathrm{In}}^{115}$, ${\mathrm{I}}^{127}$, and ${\mathrm{Ta}}^{181}$ have been measured in the incident neutron energy range from 130 to 1800 keV. The results agree rather well with other activation measurements. The activation cross sections are combined to form the total neutron-capture cross sections of the natural elements and compared with the capture gamma-ray data of Diven et al. and Gibbons et al. The elemental cross sections agree rather well with the results of Diven et al. but do not agree with the lower results of Gibbons et al.
