A STUDY OF NEUTRON PRODUCING REACTIONS BY DEUTERON BOMBARDMENT OF B$sup 1$$sup 1$
The neutrons produced by deuteron bombardment of thin, enriched B/sup 11/ target were studied for nlne different deuteron energies ranging from 1.60 to 2.70 Mev. The absolute differential cross sections for the production of neutrons feeding well established states in C/sup 12/ were determined. Besides the monoenergetic neutron groups feeding the states of C/sup 12/, previously unreported continuum neutrons due to many body break-up of deuteron plus B/sup 11/ system were observed and analyzed. The break-up 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 +/), B = +1.00 Mev states were studied in detail. The effect of compound resonance at E/sub delta / = 2.18 Mev on the angular distributions of the above neutron groups was studied. The investigations were performed employing time-of-flight technique utilizing pre-acceleration pulsed, post-acceleration bunched deuteron beam from a 3 Mev Van de Graaff accelerator.
