Abstract
A signature S-d(y) of isoscalar spin-transfer strength has been tested in the inelastic scattering of 400 Mev deuterons from C-12. It was ap plied to search for Delta S=1 Delta T=0 strength in Ca-40 and C-12. In Ca-40, spin excitations were found in the 9 MeV region and over a bro ad range in the continuum with a cluster of strength around 15 MeV. In C-12, Delta S=1 Delta T=0 levels were observed at 12.7 MeV (well know n T=O 1(+) level), 18.3 MeV (2(-) T=0 level) and 20.4 MeV. Resonances were found at 20 MeV and at 30 MeV. Beyond 35 MeV the Delta S=1 Delta T=0 response is similar to the one observed in Ca-40. Microscopic DWIA calculations agree nicely with the C-12 data.
