Abstract
The very neutron-rich nucleus has been investigated by inelastic scattering on and liquid hydrogen targets. Through distorted wave analysis, the reduced electric quadrupole transition probability (stat) and the neutron transition probability (stat) have been derived. A simple shell model calculation has shown a need for a factor of about 0.4 decrease of the normal polarization charges to elucidate the results. This is interpreted as a decoupling of the valence neutrons from the nuclear core in carbon isotopes heavier than .
