Alpha transfer mechanism in heavy-ion reactions
Journal Article

· Phys. Rev. C; (United States)
In some heavy-ion reactions, such as /sup 24/Mg(/sup 16/O,/sup 12/C)/sup 28/ Si oscillatory structure often appears in the whole angle region in the differential cross section. This anomalous phenomenon, unexpected from ordinary distorted-wave Born approximation theory, is explained by an alpha transfer process between two unidentical nuclear cores. Nuclear molecular-orbit theory has been formulated, and the coupled system of wave equations describing both the elastic scattering and transfer reaction channels are obtained. An independent ..cap alpha.. particle model is assumed in the evaluation of nuclear wave functions. The differential cross sections of both channels have been calculated simultaneously for two cases: /sup 24/Mg(/sup 16/O,/sup 16/O)/sup 24/ Mg and /sup 24/Mg(/sup 16/O,/sup 12/C)/sup 28/ Si as well as /sup 28/Si(/sup 16/O,/sup 16/O)/sup 28/ Si and /sup 28/Si(/sup 16/O,/sup 12/C)/sup 32/ S. Agreement with the experimental data can be reached in the whole angle region for both of these cases.
