The 12C(p,2p)l1B reaction has been measured at 100 MeV in both symmetric and asymmetric geometries. Distorted wave impulse approximation calculations were used to obtain spectroscopic factors for all states of l1B below 7 MeV excitation. From these spectroscopic factors and the shapes of the measured angular correlations, it is concluded that (i) no large 1f components are present in the wavefunction of the ground state of 12C and (ii) this experiment gives no evidence for the formation of giant resonances as the intermediate step in multistep reaction processes to the 4·44 MeV (5/2-) and 6·74 MeV (7/2-) states of 11B.

have been observed at high excitation energies. These data may serve as a basis for judging the validity of models which treat the equilibration of the entrance-channel energy between the fragments as well as models of the direct-fission process. As far as the angular-momentum transfer process is concerned, possible biasing of the I distribution due to fission, and a primary depolarization of the heavy fragment's intrinsic angular momentum, provide us with an alternative explanation of the measured out-of-plane fission widths which seems more consistent with y-anisotropy data. Thus the sequential-fission process following a deep-inelastic collision seems to be more intriguing than expected insofar as the population of new modes in deep-inelastic collisions is concerned.We present data for the reaction ^^Ca(^,2^;^^K at 148.2 MeV. Energy sharing cross sections for the f"^ ground state and J"^ excited state are well described by distortedwave im^pulse-approximation calculations. An explicit comparison of the results of the factorization approximation with these experimental results provides considerable support for the usual distorted-wave impulse-approximation treatment.
