Nuclear Structure ofPb205from the (d,t) Reaction

The structure of ${\mathrm{Pb}}^{205}$ has been investigated using the neutron pickup reaction ${\mathrm{Pb}}^{206}\mathrm{}(d,t)\mathrm{}{\mathrm{Pb}}^{205}$ at a bombarding energy of 21.6 MeV. A distorted-wave analysis (DWA) has been made of the angular distributions of seven triton groups that excite ten levels in ${\mathrm{Pb}}^{205}$. The spectrum is sparse; most of the strength corresponding to pickup from a given orbital in the target is contained in a single level. Configuration assignments and spectroscopic factors derived from the DWA are found to agree well with a shell-model calculation of the structure of ${\mathrm{Pb}}^{205}$ by Miranda.
