Identification of new excited levels in /sup 28/Si through the /sup 27/Al(d,n)/sup 28/Si reaction

Neutron spectra from the /sup 27/Al(d,n)/sup 28/Si reaction have been measured with an energy resolution of better than 10 keV. Bombarding energies ranged from 2.5 to 8 MeV, permitting various regions of excitation in /sup 28/Si to be populated with 1 to 3 MeV outgoing neutrons. Levels corresponding to contaminants could be identified by the energy shift with angle. We have identified four new levels below 13 MeV and 22 new levels above 13.4 MeV. The (d,n) reaction at low bombarding energies appears to be nonselective; we observe every previously known level as well as the new ones, with the only exception being those which are unresolved (E/sub 1/-E/sub 2/< or approx. =8 keV) from neighboring levels. We are not able to deduce the spins and parities of these levels from the present data.
