Abstract

The partial one-neutron removal cross section of 24O leading to the first excited state in 23O has been measured to be 65.7 ± 5.3 mb with a proton target in inverse kinematics at the beam energy of 62 MeV/nucleon. The decay energy spectrum of the neutron unbound state of 23O was reconstructed from the measured four momenta of 22O and the emitted neutron. A sharp peak was observed at E decay = 48 ± 3 keV, confirming the previous measurements. The measured partial longitudinal momentum distribution of 23O * showed the d-wave knockout character, providing a support for the Jπ assignment of 5/2+ for this state. The spectroscopic factor for the neutrons in 0d5/2 orbital was deduced, for the first time, to be C2S(0d5/2) = 3.7 ± 0.3 (preliminary) by comparing with the result of Glauber model. The relatively large spectroscopic factor supports the N = 16 shell closure in the neutron drip-line nucleus 24O.
