摘要

The electric dipole strength above the one-neutron separation energy has been measured in the neutron-rich nucleus 52Ca using the Coulomb excitation at 223 MeV/nucleon in inverse kinematics. The γ-ray detector array CATANA, the neutron detector NeuLAND demonstrator, and the SAMURAI spectrometer at RIKEN Nishina Center were combined to reconstruct the excitation energy of 52Ca. A observed sharp peak at the very low neutron energy in the 52Ca → 51Ca +n channel indicates that 52Ca has a sizable amount of dipole strength just above the one neutron threshold.
