Abstract
The reaction 93Nb(π+,π−)93Te has been measured in the energy range Tπ=30–60 MeV at various scattering angles. At all energies the groundstate transition could be observed, whereas the transition to the double isobaric analog state has been identified unambiguously only at Tπ=50 MeV. The groundstate transition exhibits a pronounced resonance-like energy dependence which extends the systematics of this peculiar feature to heavy nuclei. An explanation within the d′ hypothesis is presented.
