Abstract

The spectra of levels in the hypernuclei $_{\ensuremath{\Lambda}}^{13}\mathrm{C}$, $_{\ensuremath{\Lambda}}^{14}\mathrm{N}$, and $_{\ensuremath{\Lambda}}^{18}\mathrm{O}$, excited by 800-MeV/c kaons in the (${K}^{\ensuremath{-}}$,${\ensuremath{\pi}}^{\ensuremath{-}}$) reaction, have been observed at the Brookhaven alternating-gradient synchrotron. Data were recorded for scattering angles from 0\ifmmode^\circ\else\textdegree\fi{} to 25\ifmmode^\circ\else\textdegree\fi{}, corresponding to momentum transfers from 50 to 330 MeV/c. The levels are interpreted in terms of a $\ensuremath{\Lambda}$ hyperon coupled to a strangeness-zero nuclear core. The results provide insights into the properties of the $\ensuremath{\Lambda}$-nucleon and $\ensuremath{\Lambda}$-nucleus interactions.
