Abstract

Measurements of the breakup and the neutron removal reactions of C16 have been made at 46 MeV∕A and the decay cross sections measured. A correlation between the cluster breakup channels and the reaction Q value suggests that the reaction mechanism is strongly linked to quasielastic processes. No enhancement of the two-body cluster breakup cross section is seen for C16. This result would indicate that C16 does not have a well developed cluster structure in the ground state, in agreement with recent calculations.
