The Excited States of theN13Nucleus

The properties of the excited states of ${\mathrm{N}}^{13}$ were reinvestigated by applying dispersion theory to the ${\mathrm{C}}^{12}(p, p){\mathrm{C}}^{12}$ differential cross section reported in the preceding paper. The quantity and accuracy of the data were sufficient to permit extraction of the experimental $S$ wave phase shift up to 1.4 Mev. The remainder of the data was fitted by successive readjustment of the level parameters.
