Description

It is shown that localization of the low-energy isoscalar 1- strength observed in a recent Groningen experiment may be caused by incompressible flow vibrations with considerable contribution of a solenoidal component. Calculations performed here without free parameters predict the energy of the isoscalar low-energy dipole resonance of the order of 40 A-1/3, MeV. This estimate agrees well with data obtained on 90Zr and 208Pb. (orig.)
