Splitting of the Dipole and Spin-Dipole Resonances

Cross sections for the 90,92,94Zr(p,n) reactions were measured at energies of 79.2 and 119.4 MeV. A phenomenological model was developed to describe the variation with bombarding energy of the position of the L=1 peak observed in these and other (p,n) reactions. The model yields the splitting between the giant dipole and giant spin dipole resonances. Values of these splittings are obtained for isotopes of Zr and Sn and for 208Pb.Comment: 14 pages, 4 figure

Cross section and analyzing power in the /sup 206/Pb(. -->. t,p) /sup 208/Pb(4/sup -/) reaction. [17 MeV, mechanism study]

Cross sections and analyzing powers were measured in the /sup 206/Pb(..-->..t,p) /sup 208/Pb reaction leading to the 4/sup -/, 5/sup -/ states of the (p/sub 1/2//sup -1/ g/sub 9/2/) doublet. Standard DWBA calculations reproduce the cross section but not the analyzing power for the 5/sup -/ state. The opposite is true for a sequential transfer (t,d) (d,p) calculation for the 4/sup -/ state. 1 figure, 1 table

Core-coupled states excited in the /sup 208/Pb(d vector,t)/sup 207/Pb reaction. [17 MeV]

A study of known core-excited states in /sup 207/Pb shows that the cross section and analyzing power data are not well reproduced by two-step mechanisms. 3 figures
