Abstract
We investigate theoretically whether it is feasible to detect η- and ω-nucleus bound states. As well as the closed shell nuclei, <sup>16</sup>O, <sup>40</sup>Ca, <sup>90</sup>Zr and <sup>208</sup>Pb, we also investigate <sup>6</sup>He, <sup>11</sup>B and <sup>26</sup>Mg, which are the final nuclei in the proposed experiment involving the (d,<sup>3</sup>He) reaction at GSI. Potentials for the η and ω mesons in these nuclei are calculated in local density approximation, embedding the mesons in the nucleus described by solving the mean-field equations of motion in the QMC model. Our results suggest that one should expect to find η- and ω-nucleus bound states in all these nuclei. © 1998 Elsevier Science B.V. All rights reserved.
