Abstract: Precise reaction cross sections (σR) for ^<24−38>Mg on C targets at energies around 240 MeV/nucleon have been measured at the Radioactive Isotope Beam Factory at RIKEN. The σR for ^<36−38>Mg have been measured for the first time. An enhancement of σ_R compared to the systematics for spherical stable nuclei has been observed, especially in the neutron-rich region, which reflects the deformation of those isotopes. In the vicinity of the drip line the σ_R for ^<37>Mg is especially large. It is shown by analysis using a recently developed theoretical method that this prominent enhancement of σ_R for ^<37>Mg should come from the p-orbital halo formation breaking the N=28 shell gap.
