Breakup Reactions of Drip-Line Nuclei Near N = 20, 28

The one-neutron removal cross section from 29 Ne, 33,35,37 Mg, and 39,41 Si on a Pb target have been measured at around 240 MeV/nucleon at the RIBF (RI-Beam Factory) at RIKEN. This main goal of the experiment was to extract the inclusive Coulomb breakup cross sections in order to probe possible halo structures through their enhanced low-energy E1 strengths - so-called soft E1 excitations. The results showed significant enhancement of the one-neutron removal Coulomb breakup cross section for 37 Mg. This in turn provides evidence for the existence of halo structure in 37 Mg.
