T(d, n)He4Reaction

The differential cross sections for neutron production in the $\mathrm{T}(d, n){\mathrm{He}}^4$ reaction have been measured over the deuteron bombarding-energy range 0.25 to 7.0 Mev. Legendre polynomial fits to the data are presented and compared with existing data. The total cross section plotted as a function of deuteron energy has an anomalous behavior which may indicate a broad level in ${\mathrm{He}}^5$ near 20-Mev excitation energy.
