Energy Levels inHo166

The energy levels in ${\mathrm{Ho}}^{166}$ are studied by means of ($d, p$) reaction spectroscopy and a $Q$ value of 4025±7 keV is obtained for the ground state. A rotational model is used to interpret the energies and generate state vectors for the experimental levels. Using these vectors and the distorted-wave Born approximation, a theoretical ($d, p$) spectrum is constructed and compared with the experimental data.
