Resonating-group study ofN+O16scattering with a generator-coordinate technique

The scattering of nucleons by $sup 16$O is studied with the resonating- group method. The $sup 16$O wave function used is a translationally invariant antisymmetrized product of single-particle wave functions of (1s)$sup 4$(1p)$sup 12$ configuration in a harmonic-oscillator well having an appropriately chosen width parameter. A generator-coordinate technique is employed to facilitate the computation of the nonlocal interaction between the nucleon and the $sup 16$O nucleus. This technique is discussed in some detail in order to demonstrate its utility in a nuclear problem involving a relatively large number of nucleons. Calculated results are compared with experimental data over a wide range of energies, and it is found that the agreement is in general quite satisfactory. Also, the result shows that in this particular problem the heavy-particle pickup process, which is properly taken into consideration by the use of a totally antisymmetric wave function, has a relatively small contribution.
