Book Description
In the last few years it has become clear that the effect of the shifting centers of mass (recoil effect) have to be properly incorporated into the theory of single nucleon transfer between nuclei, especially at higher energies. A re-examination of the present theory reveals, however, that there remains a serious problem, which is associated with the so-called spurious center of mass motion in nuclear structure models. In principle the present calculations that purport to treat recoil exactly, nonetheless ought to be corrected for the above defect in the nuclear wave functions that they employ. An exact resolution of the long outstanding problem of spurious center of mass motion in nuclear models has not been obtained, but an approximate procedure for handling the correction to reaction calculations arising from this source has been formulated. The correction has two components. There is a scalar one which corresponds merely to a scaling of the radial coordinate and applies to all reactions. There is also a vector correction which can be cast into a form in which a particle picked up or removed from a definite shell model state appears to occupy a distribution of states having the same parity but differing in angular momentum. This component of the correction applies only to certain reactions. Because of the dispersion in the apparent angular momentum of the transferred nucleon, the reaction can proceed through the transfer of larger units of angular momentum than the normal recoil calculations allow, and the correction therefore is expected to grow with increasing bombarding energy. The scheme developed for handling this effect, which might be referred to as bound state recoil to distinguish it from the recoil effect that the current theories focus on, is presented together with preliminary estimates of its importance.

Book Description
Two-nucleon-transfer reactions induced by heavy ions have been particularly successful in pointing out contributions of inelastic two-step processes. They provide a way to investigate the overlap between the wave functions of excited states of the target and residual nuclei. However, calculations of absolute cross sections must take into account sequential transfer. The studies of the (16O, 12C) reaction on 1s--0d- and 0f--1p-shell nuclei are reviewed. The relative spectroscopic factors are in good agreement with those of the (6Li, d) and (12C, 8Be) reactions; hence, this reaction is evidently a good .cap alpha.-transfer reaction. However, some puzzling results are still not understood: excitation of unnatural-parity states in s--d shell-nuclei, the failure of EFR-DWBA calculations in reproducing the angular correlation measurements. Several experimental results showing that the 28Si(18O, 14C)32S reaction is not a good .cap alpha.-transfer reaction are presented. 11 figures, 4 tables.
