Q values and differential cross sections have been measured for nuclear states in Bi 210 excited by the Bi 209 (d,p) reaction. A previously unobserved group with Q = 2.35=b0.03 Mev has been found, corresponding to a state with probable proton-neutron assignment (^9/2^9/2). The observed Q value for this state is in good agreement with the Q value expected for the 1 -ground state of RaE. Groups of states with mean excitation of 0.41, 0.88 and 1.4, 2.02, 2.56, 2.81, 3.15, and 4.03 Mev have been found, and neutron assignments of g 9 / 2> iu/2, db/2, S1/2, £7/2, ^3/2, and (^11/2) have been suggested. A comparison with theoretical calculations by Newby and Konopinski for the (hi^gm) group of states gives further support to their observation that a calculation of levels in the neighborhood of Pb 208 is far less accurate when the extra-core interaction type is protonneutron than when it is neutron-neutron or proton-proton.

The spectra of protons from (d,p) nuclear reactions initiated by 11-Mev deuterons incident on Th 232 , U 233 , U 235 , U 238 , and Pu 239 have been obtained using separated isotopic targets. The protons were analyzed in a double-focusing magnetic spectrometer. States with assignments known from radioactive-decay studies are identified and assignments for some other observed states are discussed using the Nilsson model and Satchler's theory of (d,p) reactions in deformed nuclei. From an analysis of the results the following binding energies of the last neutron are obtained: U 234 , 6.83±0.11 Mev; U 239 , 4.74±0.06 Mev; and Pu 240 , 6.49±0.05 Mev.
