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 J^π assignment of 5/2⁺ for this state. The spectroscopic factor for the neutrons in 0d_5/2 orbital was deduced, for the first time, to be C²S(0d_5/2) = 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.
