Cross Section and Angular Distribution of theHe3(d,p)He4Nuclear Reaction

The cross section for the reaction ${\mathrm{He}}^3\mathrm{}(d,p)\mathrm{}{\mathrm{He}}^4$ has been studied for deuteron energies from 188 kev to 1597 kev. The yield of protons at 0° to the deuteron beam exhibits a maximum at 400-kev deuteron energy. At this energy the angular distribution of the disintegration particles is spherically symmetrical and the total cross section is 0.69×${10}^{-24\mathrm{}}$ ${\mathrm{cm}}^2$. At higher energies there is a preferential emission of protons at 0°. At 1600 kev the ratio of the number of protons at 0° to that at 90° is 1.08. The variation of total cross section with bombarding energy agrees with a calculated single level resonance formula from 188 kev to 600 kev. At higher energies the theoretical values give too small a cross section.
