Abstract

Inelastic proton scattering to the 21+ state of neutron-rich C16 is studied in inverse kinematics using a 33-MeV/nucleon beam. The deformation parameter βpp'=0.47(5) obtained is consistent with the global systematics of even-even nuclei, based on the homogeneous quantum liquid-drop model. This result contrasts that of a recent lifetime measurement for the 21+ state in C16, where an anomalously reduced E2 transition strength is observed. A combination of these two results yields a large Mn/Mp ratio of about 7, indicating a dominant neutron contribution to the quadrupole collectivity.
