Abstract

The optical potential for the η-meson is calculated. This is based on a new determination of a large η-N scattering length and recent experiments of η production in two nucleon collisions. These determine the η - nuclear potential well to be about 45 MeV deep and able to support S, P, D and F quasibound states. Some of the higher angular momentum states are fairly narrow and offer a chance of experimental detection.
