Low-energy isoscalar dipole strength in ⁴⁰Ca, ⁵⁸Ni, ⁹⁰Zr and ²⁰⁸Pb

The 1 ħω low-energy isoscalar dipole strength has been studied in ²⁰⁸Pb, ⁹⁰Zr, ⁵⁸Ni and ⁴⁰Ca, using the (α, α'γ ₀) reaction at 0°. The fraction of the isoscalar dipole EWSR exhausted by the observed 1 ^- states in the four nuclei is at maximum 14.7%, 8.0%, 5.0% and 4.3%, respectively.
