Low-Lying Energy Levels inSc41

The reaction ${\mathrm{Ca}}^{40}(d, n){\mathrm{Sc}}^{41}$ was studied at 4.15-Mev bombarding energy using nuclear emulsions as detectors. Four groups of neutrons were observed with $Q$ values of -0.57, -2.43, -2.64, and -2.85 Mev. The observed angular distributions can be fitted with distirbution curves obtained from stripping analysis on the basis of $r_0=6.0\mathrm{}$ fermi and $l_p=3, 1, 1, 1$, respectively. Two additional groups of questionable assignment were observed at $Q=-1.13\mathrm{} \mathrm{and} -1.41\mathrm{}$ Mev. Neutron groups from reactions on ${\mathrm{C}}^{12}$ and ${\mathrm{O}}^{16}$ were also observed and served to confirm the beam calibration as well as background and other correction methods.
