Title: Neutron-dominant quadrupole collective motion in {sup 16}C

Abstract

Inelastic proton scattering to the 2{sub 1}{sup +} state of neutron-rich {sup 16}C is studied in inverse kinematics using a 33-MeV/nucleon beam. The deformation parameter {beta}{sub pp{sup '}}=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 2{sub 1}{sup +} state in {sup 16}C, where an anomalously reduced E2 transition strength is observed. A combination of these two results yields a large M{sub n}/M{sub p} ratio of about 7, indicating a dominant neutron contribution to the quadrupole collectivity.
