Abstract
The resonating-group method is used to study the ..cap alpha..+/sup 16/O system. The cluster internal functions used are translationally invariant antisymmetrized products of single-particle wave functions of the lowest configuration in harmonic-oscillator wells, with width parameters chosen to yield the correct rms radii of both the ..cap alpha.. and the /sup 16/O clusters. A generator-coordinate technique is employed to derive the integrodifferential equation which governs the relative motion between the clusters. The result shows that a fairly satisfactory description of the /sup 20/Ne rotational bands can be obtained. In addition, it is found that, with the introduction of a phenomenological imaginary potential to take reaction effects into account, the calculation also yields differential scattering cross sections which agree rather well with experimental data.
