Halo structure in 19C: a Glauber model analysis Original Research Article

The recently available 19C+12C interaction cross section data at Elab=960A MeV and the longitudinal momentum distribution data at Elab=910A MeV and 88A MeV have been analyzed in a Glauber model approach to investigate the possible ground state configuration of the 19C nucleus. A comparative analysis of both these experimental data fails to yield a consistent conclusion regarding possible ground state configuration within the 1σ experimental error bar. It is suggested that a considerable change of the core of 19C from the bare 18C nucleus may take place.
