Isoscalar E0, E1, and E2 strength in ⁴⁴Ca

NUCLEAR REACTIONS ⁴⁴Ca(α, α'), E=240 MeV; measured Eα, Iα, angular distributions using multipole-dipole-multipole (MDM) spectrometer at Texas A and M K500 superconducting cyclotron. ⁴⁰Ca; deduced isoscalar giant monopole and quadrupole resonances (ISGMR and ISGQR), widths, E0, E1 and E2 strengths, energy-weighted sum rule (EWSR). Strength distributions compared with the predictions of Hartree-Fock based random phase approximation calculations with the KDE0v1 Skyrme-type interaction.
