Research in nuclear chemistry. Annual progress report, September 15, 1975--December 31, 1976. [Dept. of Chemistry, Carnegie-Mellon Univ. , Pittsburgh]
Experimental studies in which the perturbations of gamma-ray angular correlations were used to observe and measure the interactions of nuclear moments with chemically generated electric field gradients are reported. Such quadrupole interactions can provide detailed information on molecular structure and chemical bonding. Experiments were completed with /sup 181/Hf binding to Vitamin B/sub 12/ and /sup 181/Hf and /sup 111/Ag probes in DNA, as well as /sup 181/Hf studies of several inorganic compounds containing Hf--oxygen and Hf--phosphate bonds. Experimental research programs in heavy-ion nuclear reactions studies were initiated at several major accelerator facilities. The energetic fragments from heavy-ion transfer reactions on medium mass targets were investigated by using a counter telescope with element and mass resolution. Some results from /sup 65/CU + /sup 12/C at 130 MeV are presented. The emissions of H and He in hard grazing collisions of /sup 86/Kr with /sup 197/Au are being measured at the SuperHILAC. In this experiment, both singles measurements of the light charged particles and coincidence observations with deep inelastic processes are in progress. In a related, but distinct, experiment the fusion, fission, and charged-particle-emission probabilities for /sup 194/Hg compound nuclei excited to 97.5 MeV by different reactions using matched heavy-ion beams are being studied. 26 figures, 5 tables.
