Abstract
We study strangeness-changing response functions as an alternativedescription of hypernuclear structure. Hypernuclear states are treatedin the same manner as any other conventional nuclear excitation thatemerges from the response of the nuclear ground state to an externalprobe. The nuclear response is calculated using a random-phaseapproximation to an effective relativistic mean-field model thatreproduces bulk properties of normal nuclei. The relevant meson-baryonvertices are constrained by imposing SU(3)-flavour symmetry, while theresidual hyperon-particle-nucleon-hole interaction is assumed to bemediated by the two lightest S = -1 mesons: the pseudoscalar kaonand its vector partner K*(892). We use this model to analysethe spectra of 16YO and 40YCa hypernuclei.
