NUCLEAR STRUCTURE STUDIES IN THE LEAD REGION WITH (d,t) REACTIONS
S>Energy distributions of tritons from (d,t) reactions in the isotopes of lead, bismuth, and thallium were measured with approx equal 100 kev resolution. Evidence is given on the location of the missing h/sub 9/2/ state in Pb/sup 207/. As theoreticall y expected, the spectrum from Bi/sup 209/(d,t) is quantitatively similar to that from Pb/sup 208/(d,t) except that all levels are split into two or more components. The energies of the sthtes excited by Pb/sup 207/(d,t) agree well with those predicted from the True and Ford calculation. The cross sections for exciting these agree reasonably well with calculations from the True and Ford wave functions; but several changes in the latter are suggested, including a reduction of the (p/sub 1/2/)-/sup -2/ configuration in the ground state from 73 to about 55%. The long sought 0/sup +/ state apparently occurs at 1.19 Mev. The spectra from Pb/sup 206/(d,t) and from Tl/sup 205/(d,t) show marked similarities to each other and a general similarity with the spectrum from Pb/sup 208/(d,t); it is shown that this is to be expected. In general, the shell model of nuclear structure with inverse, stripping reaction theory gives a satisfactory quantitative explanation of all the data. (auth)
