Peak Value

The neutron yield resulting from photoneutron reactions in Lu175 has been measured as a function of peak bremsstrahlung energy up to 23 Mev. The threshold energy for this reaction was found to be 7.77 ± 0.05 Mev. The giant resonance cross section has a peak value of 225 millibarns at 16 Mev., a half-width of 8.4 Mev., and an integrated cross section to 23 Mev. of 1.9 Mev-barns.

Near Threshold

The variable charge, Coulomb-projected Born (VCCPB) approximation is applied to the calculation of cross sections for electron impact 11S–21S excitation in heliumlike ions (3 ≤ Z ≤ 8 and Si12+, Ca18+, and Fe24+). Differential and total cross sections have been reported for incident energies ranging from near threshold to five times threshold energy and are compared with other available theoretical estimates.
