Large angle correlations in 40 MeV/nucleon /sup 12/C+C

Journal Article · · Phys. Rev. C; (United States)
We report measurements for in-plane and out-of-plane correlations for p,d,t,/sup 3/He, and /sup 4/He from 40 MeV/nucleon C+C. Silicon-NaI light particle telescopes were placed at (theta,phi) = (45/sup 0/,90/sup 0/) and (45/sup 0/,180/sup 0/) and another telescope was moved from theta = 25/sup 0/ to 120/sup 0/ at phi = 0/sup 0/. No peak was observed in the ratio of in- to out-of-plane proton-proton correlations at energies corresponding to quasi-elastic scattering. The angular distributions of the ratio of in- to out-of-plane for p-p, d-d, t-t, /sup 3/He-/sup 3/He, and /sup 4/He-/sup 4/He peak around 35/sup 0/ and the maximum value increases monotonically with mass of the particles reaching a value near 4 for /sup 4/He-/sup 4/He. A calculation incorporating simple kinematic effects cannot reproduce the observed correlations for any of the paritcle pairs.
