ResumoExcitation curves for the reactions 115 In(n,n′) 115 In m , 113 In(n,n′) 113 In m , and 115 In(n,2n) 114 In m have been measured by the activation method. The neutron flux at energies below 5.1 MeV was determined with a calibrated neutron long counter while at higher energies, measurements were made relative to the known cross section for the 32 S(n,p) reaction. Effective cross sections for a 235 U fission-neutron spectrum calculated from our measured excitation curves are 173 ± 9 mb for 115 In(n,n′) 115 In m , 123 ± 24 mb for 113 In(n,n′) 113 In m , and 0.64 ± 0.06 mb for 115 In(n,2n) 114 In m .
