REACTION C$sup 12$(d,n)N$sup 1$$sup 3$
The reaction C/sup 12/(d,n)N/sup 13/ has Q = -0.28 Mev and so is expected to show strong direct interaction effects even at low energies of the bombarding deuterons. An extensive study was made of this reaction at 14 values of the deuteron energy between Ed= 1.45 Mev and Ed = 2.95 Mev. At each deuteron energy the differential cross section was measured at about 20 angles between 0 and 165 deg . Neutron time-of-flight techniques were used and each point on each angular distribution represents the detection of at least 10/sup 3/ neutrons. Direct interaction effects are seen at all bombarding energies in the backward as well as in the forward hemisphere. The differential cross section at 0 deg shows very pronounced "resonance" structure but this largely disappears in the integrated cross section and is due chiefly to interference between the direct interaction term and the probably quite small compound nucleus contribution. A rough method for eliminating the interference terms between the two mechanisms in the differential cross section is proposed and applied. The resultant "purified" angular distribution Is remarkably close, in the forward hemisphere, to that predicted by simple stripping theory. A backward maximum, much lower than the forward peak, is also present but not accounted for. (auth)
