Energy Levels ofSi28

Abstract

The neutron spectrum from the ${\mathrm{Al}}^{27}(d, n){\mathrm{Si}}^{28}$ reaction has been investigated at eight angles by means of nuclear emulsions. The energy of the incident deuterons was 2.167±0.015 Mev. The data indicate energy levels of ${\mathrm{Si}}^{28}$ at 1.78±0.10, 4.54±0.2, 4.95±0.2, 6.24±0.06, 6.88±0.06, 7.39±0.06, 7.89±0.06, 8.31±0.10, 8.57±0.08, 9.37±0.04, 10.00±0.10, and 10.25±0.06 Mev.
