Population of High-Lying Three-Nucleon-Cluster States in ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$ and ${}_{}{}^{19}{}_{}{}^{}\mathrm{Ne}$

The analog reactions ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$(${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$, ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$)${}_{}{}^{19}{}_{}{}^{}\mathrm{Ne}$ and ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$(${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$, ${}_{}{}^7{}_{}{}^{}\mathrm{Be}$)${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$ at 100 MeV have been utilized to study high-excitation, three-nucleon-cluster states in ${}_{}{}^{19}{}_{}{}^{}\mathrm{Ne}$ and ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$. Deformed-model calculations have been made in order to predict the energies of such high-lying states in terms of rotational bands with one or more particles in the $\mathrm{fp}$ shell. These show that the high-lying levels seen in the data can be explained by ${\mathrm{}\left(\mathrm{sd}\right)\mathrm{}}^2$ ${\mathrm{}\left(\mathrm{fp}\right)\mathrm{}}^1$ and ${\mathrm{}\left(\mathrm{fp}\right)\mathrm{}}^3$ configurations outside an ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ core.
