Single proton knock-out reactions fromF24,25,26

The cross sections of the single proton knock-out reactions from $^{24}\mathrm{F}$, $^{25}\mathrm{F}$, and $^{26}\mathrm{F}$ on a $^{12}\mathrm{C}$ target were measured at energies of about $50\phantom{\rule{0.3em}{0ex}}\text{MeV}∕\text{nucleon}$. Ground state populations of $6.6\ifmmode\pm\else\textpm\fi{}0.9\phantom{\rule{0.3em}{0ex}}\text{mb}$, $3.8\ifmmode\pm\else\textpm\fi{}0.6\phantom{\rule{0.3em}{0ex}}\text{mb}$ for the reactions $^{12}\mathrm{C}(^{24}\mathrm{F},^{23}\mathrm{O})$ and $^{12}\mathrm{C}(^{25}\mathrm{F},^{24}\mathrm{O})$ were extracted, respectively. The data were compared to calculations based on the many-body shell model and the eikonal theory. In the reaction $^{12}\mathrm{C}(^{26}\mathrm{F},^{25}\mathrm{O})$ the particle instability of $^{25}\mathrm{O}$ was confirmed.
