Abstract
Excitation of spin transitions using electromagnetic and hadronic probes is discussed. Spectroscopic strengths are deduced from studies of (e,e'), (p,p'), (π,π') and (p,n) for selected states. The missing isovector and isoscalar strengths imply the existence of other important quenching mechanisms since the Δ-N-1 mechanism does not contribute to high spin excitations or to isoscalar transitions. The stretched states are used as benchmarks to test the nucleon-nucleon tensor force in proton scattering and the pion-nucleon spin orbit force in pion scattering. The results are in striking agreement with predictions of the DWIA model
