Description
We extend the method of time delay proposed by Eisenbud and Wigner, to search for unstable states formed by η mesons and the 3He nucleus. Using few-body equations to describe η3He elastic scattering, we predict resonances and unstable bound states within different models of the η-N interaction. The η3He states predicted within this novel approach are in agreement with the recent claim of the evidence of η-mesic 3He made by the TAPS Collaboration. (letter to the editor)
