PION-SCATTERING TO 6(-) STRETCHED STATES IN S-32

Inelastic pi(-+) differential cross-section measurements at a pion inc ident energy of 162 MeV were made for 12 (f(7/2)d(5/2)-1) 6(-) states in S-32, including four tentative new isoscalar states. Isoscalar and isovector mag netic structure coefficients were determined for each st ate by combining the pion data with previous electron scattering data. The trend of small isoscalar/isovector strength ratios continues in S -32, With the isovector strength being comparable to theoretical calcu lations, but the isoscalar strength exhausting only about 17% of an ex treme-single-particle-hole model. However, this isoscalar strength is larger than that observed in other sd-shell nuclei and exhausts 75% of large-basis shell-model predictions. The substantial fragmentation of the 6(-) isovector strength observed in S-32 electron scattering, but not previously observed in other self-conjugate nuclei, appears to ex tend to the isoscalar strength and to include substantial isospin mixi ng. The general systematics of isoscalar and isovector stretched state transition strengths are reviewed.
