Signatures for isoscalar spin transitions excited in (, ') reactions

Abstract Three different signatures for isoscalar spin transitions in nuclei have been tested in the 12 C( d , d ') 12 C reaction at 400 MeV. These signatures have values of close to zero for the natural parity states, and values ranging from 0.22 to 0.50 for the ΔS =1, ΔT =0, 12.7 MeV state.
