Abstract

The energy of the first excited state of the very neutron-rich nucleus ³⁰Ne was determined by proton inelastic scattering. A liquid hydrogen target was bombarded by a beam of radioactive ³⁰Ne at 48 MeV/nucleon, and energies of the de-excitation γ rays emitted from the excited ³⁰Ne were measured. The observed transition is likely to be the one from the first 2⁺ state to the ground state of ³⁰Ne. The excitation energy, 791(26) keV, is lower than that of ³²Mg, indicating enhancement of deformation as the neutron excess increases in the N = 20 isotones. The results indicate that ³⁰Ne belongs to the 'island of inversion'.
