The partial widths for ground-state alpha-particle decay of selected excited states in [sup 15]N have been determined by measuring the production cross section and the ground-state alpha-particle decay cross section in the reaction [sup 7]Li([sup 12]C,[sup 15][ital N][sup *][r arrow][alpha]+[sup 11]B[sub g.s.])[alpha] at a bombarding energy of 90 MeV. Decay cross sections are determined by making use of a symmetry property of the decay angular correlation. The method produces agreement within experimental uncertainties for the one state for which a partial width measurement already exists, [ital E][sub [ital x]]([sup 15]N)=11.44 MeV. Reduced widths for some states place restrictions on [ital J] values previously reported.
