Natural lithium, polyethylene, and aluminum targets were bombarded with 28-Mev deuterons. The outgoing particles were analyzed with a scintillation spectrometer. The angular distributions for the following processes were measured: Li(d,d)Li, Li/sup 7/(d,d )Li/sup 7/-4.61 Mev, C/sup 12/(d,d)C/sup 12/, C/sup 12/(d d')C/sup 12/-4 43 Mev Al/sup 27/(d d)Al/sup 27/ Al/sup 27/(d d')A1/s up 27/-2.21 Mev, and H/sup 1/(d,p)H/sup 2/. The Li/sup 7/(d,d-)Li/sup 7/ 4.61- Mev angular distribution can be fitted by superimposing p1ane-wave direct- reaction curves corresponding to 1 = 0, a = 3.4 f and 1 - 2, a = 3.9 f, where a is the interaction radius and 1 the angular momentum change; this leads to an odd parity assignment for the level. The angular distribution of the reaction C/ sup 12/(d,d )C/sup 12/-4.43 Mev is fitted by superimposing the curves of 1=0, a =4.1 f and1=2with a =4.6 f. The tely fitted with a curve of 1 = 1, a = 5.1 f; therefore there follows an odd parity assignment for the level. The possible spin assignments of the levels are discussed. The inelastic scatterimg curves yield some evidence of a total reaction. The elastic scattering angular distributions show the usual diffraction pattern, and interaction radii were calculated using an optical analogy that implies the scattering of waves from a black disk. The angular distribution of the interaction H/sup 1/(d,p)H/sup 2/ is consistent wtth measurements performed at neighboring energies and it also agrees with the curve obtained with a Serber-type force.
