| Popis: | New measurements of the analyzing powers ${A}_{y}$ and ${T}_{20}$ have been obtained for the $^{2}\mathrm{H}(d,\ensuremath{\gamma})^{4}\mathrm{H}\mathrm{e}$ reaction at a laboratory beam energy of $115\phantom{\rule{0.3em}{0ex}}\mathrm{keV}$. A transition matrix element analysis results in a unique solution which indicates that the reaction proceeds by 55% $E2$, 29% $E1$, and 16% $M2$ radiation. These results are shown to be in good agreement with the results of a new refined resonating group model calculation. The impact of these results on the extrapolated value of the astrophysical $S$ factor for this reaction is discussed. |
