Abstract

The unbound excited states of the most neutron-rich dripline oxygen isotope, ²⁴O, have been investigated by using the ²⁴O(p,p′)²⁴O^{&z. ast;} reaction at the beam energy of 62 MeV/nucleon in inverse kinematics. The first and second unbound excited states of ²⁴O have been observed at E_x =4.63-0.14^0.30 MeV and E_x =4.63-0.19^0.24 MeV (preliminary) along with the evidence for another higher lying state at around 7. 3 MeV. The quadrupole deformation parameter β₂₊ was deduced to be E_x =4.63-0.14^0.30 (preliminary) for the first time. The systematics of the β₂₊ and the E_x 2₁⁺ in the Z = 8 isotopes shows the N = 16 spherical shell closure in ²⁴O.
