Isospin-mixed /sup 18/F states seen via /sup 14/N(. cap alpha. ,. cap alpha. /sub 1/)/sup 14/N(2. 31 MeV). [7. 6 to 16. 8 MeV, differential cross sections]

Extensive differential cross section measurements are reported for the isospin-forbidden reaction /sup 14/N(..cap alpha.., ..cap alpha../sub 1/)/sup 14/N over the energy range 7.6 < E/sub b/ < 16.9 MeV at 11 to 16 angles. A partial wave analysis with a new method of removing ambiguities and parametrizing S matrix elements yields the level parameters of 151 isospin-mixed, natural-parity states in /sup 18/F. These level parameters satisfactorily reproduce all the data. Many of these /sup 18/F states correspond to those seen via /sup 16/O(d, ..cap alpha../sub 1/)/sup 14/N. A number of levels have been identified as the analogs of T = 1 states in /sup 18/O. Correlations in S/sub l/(E/sub x/) suggest intermediate structure and support Friedman's bridge state hypothesis.
