Abstract:
27Ne has been investigated through the one neutron transfer reaction 26Ne(d,p)27Ne in inverse
kinematics at 9.7 MeV/nucleon. The results support the existence of a low lying negative parity state
in 27Ne which is a signature of a reduced sd-fp shell gap in the N = 16 neutron rich region, at variance
with stable nuclei.
