Abstract
The Be-9(Ar-46,Ar-45+gamma)X one-neutron removal reaction has been studied in inverse kinematics at 70 MeV/nucleon. Coincidences with gamma rays served to disentangle knockout events leading to the Ar-45 ground state. The measured partial cross section corresponds to a spectroscopic factor of 4.9(7). The residue momentum distribution is compared with new calculations based on eikonal theory and represents the first case of an L=3 neutron removal, as is expected for populating a 0f(7/2) hole in the N=28 projectile. However, the measured Ar-45 momentum distribution has a marked low-momentum tail suggestive of dissipative effects whereas the eikonal model predictions are symmetric. The angular distribution of the residues confirms that there is a deviation from the model.
