The Current Experimental Situation In Heavy-Ion Reactions

Direct-reaction contributions to projectile-fragment spectra at 10?20 MeV/nucleon

“…(9)], it is important to realize that the energy resolution employed in the experiment was not sufficient to resolve transfers to bound states, which occur at the upper limit of the spectrum but are excluded from our calculations by the continuum phase space factor employed. On the basis of a high-resolution experiment, also performed by the Berkeley group [13] it would appear that approximately the top 10MeV of the 15N spectra are transitions to bound states and should be removed before attempting a comparison with our continuum calculations. The 12C spectra, on the other hand, are shifted far enough downward by the kinematics that they contain negligible bound-state "contamination" calculated spectra "follow" the experimental ones as the incident energy changes, always peaking at an energy close to the beam velocity, and their widths are always within a factor of two of the experimental widths.…”
