Study of the $^{15}$C$(d,p)^{16}$C reaction

ORAL

Abstract

We report on a study of the neutron transfer reaction $^{15}$C($d,p)^{16}$C in inverse kinematics, using HELIOS (the HELIcal Orbit Spectrometer) at Argonne National Laboratory. Previous measurements of electromagnetic transition rates suggested exotic phenomena in $^{16}$C. The spectroscopic factors for neutron stripping provide complementary information about the wave functions of the relevant states in $^{16}$C. An 8 MeV/u $^{15}$C beam with intensity 1-2$\times 10^6$ particles per second bombarded a 110 $\mu$g/cm$^2$ CD$_2$ target. The emitted protons were transported in the HELIOS magnetic field and detected in the HELIOS silicon array. Angular distributions were measured for the lowest 5 states in $^{16}$C and relative spectroscopic factors were extracted. Mixing parameters for the two 0$^+$ states were determined. Results will be compared to shell-model calculations. Work supported by the U. S.
