The breakup reaction of neutron rich nucleus 17 N on 197 Au and 9 Be targets has been measured at RIBLL (Radioactive Ion Beam Line at Lanzhou).

The theoretical models of the cluster structures of the light neutron-rich nuclei as well as the corresponding physical mechanism and experimental approaches by breakup reaction have been introduced,which may serve as references for possible experimental studies of the cluster structure of light neutron-rich nuclei.

Based on the continuum discretized coupled channels (CDCC) theory,with the suitable initial values and boundary conditions,as well as the P3C5 algorithm to solve the coupled equations,a new code CDCCOM with higher calculation precision is written to observe the deuteron breakup effects on elastic scattering angular distributions and reaction cross sections.
