Abstract: (Elsevier)

We have investigated the loosely bound halo candidates 17 C and 19 C in a neutron+core coupling model. A deformed Woods-Saxon potential is used for the neutron-core interaction and the coupled channels equations are solved with Sturmian expansions of the relative motion wave functions for experimental one-neutron separation energies. The r.m.s. matter radii, longitudinal momentum distributions, E1 strength functions, neutron stripping cross sections and electromagnetic dissociation cross sections are calculated. Their sensitivity to the structural assumptions is explored. Available data does not allow final conclusions to be drawn for 19 C but an assessment of the possible character of 17 C and 19 C is made, and in particular, of the role of s -orbital motion between halo-neutron and core.
