Study of $^9$C via the d($^{10}$C,t)$^{9}$C reaction

ORAL

Abstract

The structure of the proton-rich nucleus $^{9}$C is poorly known. Only a few excited states have been observed and little information exists on their single-particle characteristics. The measured magnetic dipole moment is anomalously high and could suggest higher order configurations in the ground state wave function. The $^{10}$C(d,t)$^{9}$C reaction, in inverse kinematics, was used to populate states in $^{9}$C. The radioactive $^{10}$C beam was produced at the ATLAS In-flight facility through the p($^{10}$B,$^{10}$C)n reactions using a 185 MeV $^{10}$B beam incident on a cryogenic H$_{2}$ gas cell. The intensity of the secondary beam (E=171 MeV) was about 4x10$^{4}$ pps. The beam was incident on a 650 $\mu$g/cm$^{2}$ deuterated polyethylene (CD$_{2}$) target. Tritons were detected in a series of annular double sided silicon detectors covering $\theta$$_{lab}$ between 12 and 42 degrees. The heavy recoils were detected in a set of forward-angle silicon detectors in a $\Delta$E-E configuration. Preliminary results will be presented. Work was supported by the U. S. Department of Energy, Office of Nuclear Physics, under Contracts DE-FG02-04ER41320 and DE-AC02-06CH11357.
