Abstract

Stretched particle-hole states of a 0\ensuremath{\Elzxh}\ensuremath{\omega} (\ensuremath{\pi}${\mathit{d}}_{5/2}$,\ensuremath{\nu}${\mathit{d}}_{5/2}^{\mathrm{\ensuremath{-}}1}$${)}_{5}^{+}$ type were observed as low-lying isolated peaks in the high-resolution (p,n) reactions on $^{22}\mathrm{Ne}$ and $^{26}\mathrm{Mg}$ at ${\mathit{E}}_{\mathit{p}}$=35 MeV. Angular distributions of the differential cross sections have been successfully interpreted, especially at large angles, or in high-momentum transfer regions (q\ensuremath{\sim}2 ${\mathrm{fm}}^{\mathrm{\ensuremath{-}}1}$), by microscopic distorted-wave Born approximation calculations using shell-model wave functions and the M3Y interaction. No quenching of the (p,n) cross sections has been observed for these 0\ensuremath{\Elzxh}\ensuremath{\omega} stretched transitions in light nuclei.
