Incomplete-fusion reactions for {gamma}-ray spectroscopy: Application to the study of high-spin states in {sup 234}U
- Department of Nuclear Physics, Australian National University, Canberra ACT 0200 (Australia)
Incomplete-fusion reactions occur when breakup of the projectile results in only part of the beam particle fusing with the target, the remnant being emitted with an energy equivalent to the beam velocity. Such reactions have been demonstrated to populate slightly neutron-rich nuclei compared to conventional fusion-evaporation reactions, opening possibilities for the study of nuclei along the neutron-rich side of the line of stability. Results from a study of {sup 211}Po are presented to illustrate the use of incomplete-fusion reactions for {gamma}-ray spectroscopy. New results from a test-run which populated high-spin states in {sup 234}U via the {sup 232}Th({sup 9}Be,{alpha}3n) reaction are also presented. An interesting feature of the latter reaction is that the high fission probabilities for the compound nuclei which follow complete fusion, results in the residues from incomplete fusion forming the dominant residue channels.
