Correlated two-photon lines from 6-MeV/nucleon U+Th, U+U, and Th+Th collisions

Description
We find that narrow lines at 1043 and 1062 keV in the summed-energy, 1800-correlated two-photon spectrum from ≅6-MeV/nucleon U+Th collisions can be produced by cascades from high-spin states (32+) in /sup 238/U. We see no evidence for narrow two-photon lines in U+Th, Th+Th, and U+U collisions corresponding to the electron-positron lines seen by others: In the summed-energy region between 1.2 and 2.0 MeV, we set an upper limit for the cross section of 6 x 10/sup -31/ cm2 averaged over a target thickness of 1 mg/cm2
