We have studied the 2+ 1 state in neutron-rich 16Cvia inelastic proton scattering in inverse kinematics, using a 33 MeV/nucleon beam. From the angle-integrated cross-section, the deformation parameter βpp’ = 0.50(8) is obtained. This value is greater than the deformation parameter deduced from the lifetime measurement. With these two result combined, the ratio of the neutron and proton quadrupole matrix elements is deduced to be approximately 7, indicating a neutron-dominant quadrupole collectivity in 16C.
