Query: Neutron dominance in excited states of $^{26}$Mg and $^{10}$Be probed by
  proton and alpha inelastic scattering   Isospin characters of nuclear excitations in $^{26}$Mg and $^{10}$Be are
investigated via proton($p$) and alpha($\alpha$) inelastic scattering. A
structure model of antisymmetrized molecular dynamics (AMD) is applied to
calculate the ground and excited states of $^{26}$Mg and $^{10}$Be. The
calculation describes the isoscalar feature of the ground-band
$2^+_1$($K^\pi=0^+_1$) excitation and predicts the neutron dominance of the
side-band $2^+_2$($K^\pi=2^+$) excitation in $^{26}$Mg and $^{10}$Be. The $p$
and $\alpha$ inelastic scattering off $^{26}$Mg and $^{10}$Be is calculated by
microscopic coupled-channel (MCC) calculations with a $g$-matrix folding
approach by using the matter and transition densities of the target nuclei
calculated with AMD. The calculation reasonably reproduces the observed
$0^+_1$, $2^+_1$, and $2^+_2$ cross sections of $^{26}$Mg+$p$ scattering at
incident energies $E_p=$24 and 40 MeV and of $^{26}$Mg+$\alpha$ scattering at
$E_\alpha=$104 and 120 MeV. For $^{10}$Be+$p$ and $^{10}$Be+$\alpha$
scattering, inelastic cross sections to the excited states in the $K^\pi=0^+_1$
ground-, $K^\pi=2^+$ side-, $K^\pi=0^+_2$ cluster-, and $K^\pi=1^-$
cluster-bands are investigated. The isospin characters of excitations are
investigated via inelastic scattering processes by comparison of the production
rates in the $^{10}$Be+$p$, $^{10}$Be+$\alpha$, and $^{10}$C+$p$ reactions. The
result predicts that the $2^+_2$ state is selectively produced by the
$^{10}$Be+$p$ reaction because of the neutron dominance in the $2^+_2$
excitation as in the case of the $^{26}$Mg+$p$ scattering to the $2^+_2$ state,
whereas its production is significantly suppressed in the $^{10}$C+$p$
reaction.
