Investigation ofD(d, n)He3Neutrons at 8.4 Mev

Abstract

The angular distribution of neutrons from the reaction $\mathrm{D}(d, n){\mathrm{He}}^3$ has been obtained at 8.4±0.1 Mev incident deuteron energy for center-of-mass angles 2° to 84°. A single plastic crystal was used as a detector and deuterium gas at 200 psi as a target. The distribution is fitted by a sum of Legendre polynomials. It is also compared with the predictions of nuclear stripping theory, and adequate agreement is found with an angular distribution of the form $\frac{d\sigma }{d\Omega }\propto {h_d}^2-\frac{2}{3}{h}_d{h}_{d^{\prime }}+{h_{d^{\prime }}}^2$, where the $h_d$ and $h_{d^{\prime }}$ represent the simple Butler stripping distributions for the incident and target deuterons, respectively. The interaction radius necessary was $R_0=7\mathrm{}\times {10}^{-13\mathrm{}}$ cm.
