Single proton pickup reactions from 40Ca and heavy ion detection techniques

Angular distributions of the 40Ca(11B,12C)39K, 40Ca(10B,11C)39K, and 40Ca(14C,15N)39K single proton pickup reactions have been measured at beam energies of 32, 31, and 40 MeV, respectively. The (11B,12C) reaction has also been measured at 68 MeV. Angular distributions have been measured for transitions to the 39K ground state and to the first excited state. Transitions to the second excited state have also been measured for all but the 32 MeV (11B,12C) reaction. Elastic scattering data has been taken at each of these energies for use in determination of optical model potential parameters. These optical model potentials have then been used to calculate the transfer reaction angular distributions using the Distorted Wave Born Approximation (DWBA). The success of the DWBA in describing each of these reactions as well as the anomalous 40Ca(13C,14N)39K reaction is discussed. The design and construction of a new hybrid detector is also discussed. This detector allows measurement of the total energy, energy loss, point of intersection with the focal plane, and the angle of incidence over a large portion of the focal plane. All of these parameters are measured in a single detector volume with no additional windows to degrade resolution
