Identification: sources from 198Pt(γ,p) chem (1978PeZJ); from 198Pt(p,2p) E=100 MeV, chem (1976PeZW); semi γ-decay curves measured.
198Pt(pol t,α), E=17 MeV; measured σ(Eα,θ), analyzing power Ay(Eα,θ); compared with predictions of distorted wave calculation; analyzed nuclear structure with interacting boson-fermion model, U(6/4) supersymmetry, spin(6) symmetry (1983Ci01,1981Ci02,1984Ci07,1985Zh10).
Levels: All data are from 198Pt(pol t,α) (1983Ci01), except as noted.
Q-value: Note: Current evaluation has used the following Q record 2155 206901 437276 45 2003Au03
