Isoscalar E0, E1, and E2 strength in Fe54 and Zn64,68

The giant resonance region from $10\phantom{\rule{0.16em}{0ex}}\mathrm{MeV}l{E}_{x}l62\phantom{\rule{0.16em}{0ex}}\mathrm{MeV}$ in $^{54}\mathrm{Fe}, ^{64}\mathrm{Zn}$, and $^{68}\mathrm{Zn}$ has been studied with inelastic scattering of 240-MeV $\ensuremath{\alpha}$ particles at small angles, including ${0}^{\ensuremath{\circ}}$. Between 70 and $105%$ of the expected isoscalar $E0$ strength has been identified below ${E}_{x}=40\phantom{\rule{0.16em}{0ex}}\mathrm{MeV}$ for each of the nuclei. Between 71 and $108%$ of the $E1$ strength has been identified while $60%$ of $E2$ strength in $^{54}\mathrm{Fe}$ and $^{68}\mathrm{Zn}$ and $120%$ of the strength in $^{64}\mathrm{Zn}$ have been identified. The strength distributions for $^{54}\mathrm{Fe}$ and $^{64,68}\mathrm{Zn}$ are compared with the predictions from HF-RPA calculations with the KDE0v1 Skyrme interaction.
