| Abstract: | We locate resonances inη-light nucleus elastic scattering using the time delay method. We solve few-body equations within the finite rank approximation
in order to calculate the t-matrices and hence the time delay for theη-3He andη-4He systems. We find a resonance very close to the threshold inη-3He elastic scattering, at about 0.5 MeV above threshold with a width of ∼2 MeV. The calculations also hint at the presence
of sub-threshold states in both the cases |
