[102]-109). The 1- radiation following the interactions of 1271 on 197 Au and 194Pt at ELAB = 730 MeV has been studied. The beam energy is approximately 9.5% above the Coulomb barrier. The aim of the present work is to study multi-nucleon transfer to and from the target. At energies above the Coulomb barrier, stripping and pickup reactions occur, quasi-elastic and deep-inelastic events dominate, with the target-like and projectile-like fragments remaining in contact over a sufficient period of time for degree of mass and NIZ ratio equilibration to occur. Relative intensities of various target-like fragments as well as projectile-like fragments have been extracted using the RADWARE and GRAZING program respectively. The spectroscopy of the fragments has been investigated by 1-1 coincidence techniques using the AFRODITE Spectrometer from the iThemba Laboratories. Isotopes of Au and Pt have been observed as well as other nuclei having lost or gained one to two protons in the process. Q-values are also calculated and plotted versus the relative intensities. The results of these plots are compared with the predictions of the GRAZING program. The aim of the present work is to determine whether the unpaired proton from both the projectile and the target influences the transfer of nucleons and whether the transfer is done in purely statistical way or again if the unpaired proton does playa part in the transfer. It was found that for both 1271 on 197 Au and 194Pt at ELAB = 730 MeV, the maximum number of transferred nucleons was only 4- and that the predictions from the GRAZING program do not agree with the extracted relative intensities from RADWARE. 2014-08-13T20:03:45Z 2014-08-13T20:03:45Z 2005 Doctoral Thesis Doctoral PhD http://hdl.handle.net/11427/6526 eng application/pdf Department of Physics Faculty of Science University of Cape Town |
