Mass ofO21from theO18(O18,O15)O21reaction

Abstract

The mass of ${}_{}{}^{21}{}_{}{}^{}\mathrm{O}$ is measured as 8.153 ± 0.070 MeV from the $Q$ value of the ${}_{}{}^{18}{}_{}{}^{}\mathrm{O}$(${}_{}{}^{18}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{15}{}_{}{}^{}\mathrm{O}$)${}_{}{}^{21}{}_{}{}^{}\mathrm{O}$ reaction at 91 MeV.
