Odd-even staggering of reaction cross sections for 22,23,24O isotopes

Abstract

The interaction cross sections of ${}^{22,23}$O nuclei at 900 MeV/nucleon have been measured recently by Kanungo {\it et al.}. We show that the odd-even staggering parameter of interaction cross sections deduced from these new data agrees well with the theoretical systematics expected for the neutron separation energy of $S_n$=2.74$\pm$0.120 MeV for ${}^{23}$O. We also discuss briefly the energy dependence of the staggering parameter.
