Abstract

The spectra of levels in the hypernuclei CΛ13, NΛ14, and OΛ18, excited by 800-MeV/c kaons in the (K-,π-) reaction, have been observed at the Brookhaven alternating-gradient synchrotron. Data were recorded for scattering angles from 0°to 25°, corresponding to momentum transfers from 50 to 330 MeV/c. The levels are interpreted in terms of a Λ hyperon coupled to a strangeness-zero nuclear core. The results provide insights into the properties of the Λ-nucleon and Λ-nucleus interactions.
