ENERGY LEVELS OF Si$sup 29$, Si$sup 30$, AND Si$sup 31$ FROM (d,p) REACTIONS
The Si/sup 28/(d,p)Si/sup 29/ reaction was used to locate nuclear energy levels in Si/sup 29/ in the range of excitation energy between 3.5 and 9.1 Mev. The bombarding energy was 7.03 Mev and the MIT broadrange spectrograph was used to resolve the particle groups. Identification was based on a change of observation angle and a change of isotopic abundance in the target. A total of 65 levels of Si/sup 29/ was found in the range covered, 54 of which were not previously reported. In addition, l6 particle groups were assigned to the reaction Si/sup 29/(d,p)Si/sup 30/ and 7 groups to the reaction Si/sup 30/(d,p)Si/ sup 31/. The Si/sup 30/ levels lie in the range of excitation of 6.4 to 10.8 Mev, whereas the Si/sup 31/ levels lie between 2.3 and 5.5 Mev. Q-values and excitation energies are listed for all these groups. The uncertainty in Q-value for most of the levels is plus or minus 5 kev. (auth)
