Elastic and Inelastic Scattering of Protons on 14N in the Energy Region of 10 to 15 MeV. I. Experimental

Abstract

The experimental results of the 14 N( p , p ') 14 N reaction in the energy region of 10∼15 MeV were analyzed from both points of view of direct and compound-nucleus formation processes. Although the direct reaction theory reproduces the experimental results fairly well, it is not satisfactory in some aspects, especially in its poor reproduction of the rapid changes of the cross sections and angular distribution shapes with proton energy. On the other hand the compound nucleus formation theory with reasonable choices of spins and parities of the levels of the compound nucleus 15 O can reproduce well not only this energy dependence but also various aspects of the experimental results. Some theoretical considerations on the symmetry natures of the wave functions of the 14 N and 15 O states are described.
