✦ Synopsis

A novel technique with a radioactive isotope beam has been employed for in-beam γ -ray spectroscopy of a very neutron-rich isotope 34 Mg. The excited 34 Mg were produced by the projectile fragmentation reaction induced by a radioactive 36 Si beam at 50 MeV/nucleon on a 385 mg/cm 2 9 Be target. Deexcitation γ rays were detected in coincidence with the 34 Mg fragments. The measured excitation energy, 660 ± 10 keV, implies a large deformation of 34 Mg.
