NEUTRON-PRODUCING REACTIONS BY DEUTERON BOMBARDMENT OF B$sup 1$$sup 1$
The neutrons produced by deuteron bombardment of a thin, enriched B/sup 11/ target have been studied for nine different deuteron energies ranging from 1.80 to 2.70 Mev. The absolute differential cross sections for the production of neutrons feeding well-established states in C/sup 12/ were determined. In addition to the monoenergetic neutron groups feeding the states of C/sup 12/, previously unreported continuum neutrons due to many-body breakup of deuteron plus B/sup 11/ system were observed and analyzed. The breakup mechanism is inferred to be a direct reaction process rather than the compound nucleus process. The angular distributions of neutrons leaving C/sup 12/ in 15.11 Mev (1/sup +/), Q = -1.37 Mev and 12.73 Mev (1/sup +/), Q = +1.00 Mev states were studied in detail. The effect of compound resonance at E/sub d/ = 2.18 Mev on the angular distributions of the above neutron groups was studied. The investigations were performed eraploying time-of-flight technique utilizing pre-acceleration pulsed, post-acceleration bunched deuteron beam from a 3-Mev Van de Graaff accelerator. (auth)
