Study of the density distribution of 17C from reaction cross section measurement

The reaction cross section of 17 C on a carbon target at 79 A MeV has been measured by the transmission method. The density distribution of 17 C was deduced using the finite-range Glauber model (FRGM) combined with the interaction cross section of 17 C at high energy. The existence of a tail in the density distribution of 17 C is suggested to get a better understanding of both the low energy and high energy data. Under a core plus single-particle assumption, analysis shows a dominant d -wave of the valence neutron in 17 C.
