Isoscalar E 0 , E 1 , and E 2 strength in 44 Ca

Isoscalar giant resonances in $^{44}\\mathrm{Ca}$ have been studied with inelastic scattering of 240 MeV \\ensuremath{\\alpha} particles at small angles including ${0}^{\\ensuremath{\\circ}}$. A majority of the energy weighted sum rule was identified for $E0$ and $E2$ ($\\ensuremath{\\approx}70%$), and nearly half was identified for $E1$. The strength distributions are compared with the predictions from Hartree-Fock based random phase approximation calculations with the KDE0v1 Skyrme-type interaction. The giant monopole resonance energy moments for $^{40,44,48}\\mathrm{Ca}$ increase with mass, contrary to what would be expected with a negative symmetry energy, ${K}_{\\ensuremath{\\tau}}$.
