Analyzing powers and isotope ratios have been measured for ejectiles with Z7 emitted at forward angles in the 200-MeV p+natAg reaction. The observed analyzing powers are consistent with zero, and thus do not provide evidence for a significant contribution from cluster knockout, or similar direct formation mechanisms. Fragment kinetic-energy spectra above the Coulomb peak are compared with a coalescence calculation. The isotopic composition of the elemental kinetic-energy spectra is found to favor N/Z1 nuclei for fragment energies near the exit-channel Coulomb energy, whereas species with N/Z1 are more abundant in the high-energy spectral tails. This behavior is consistent with the predictions of an accreting source calculation. 1991 The American Physical Society.
