摘要：

Measurements are reported of orientation asymmetries in the forward-angle differential cross sections for pion single-charge-exchange scattering of aligned and unaligned Ho-165 nuclei. The extrapolated 0-degrees asymmetry of -0.022 +/- 0.024 indicates a quadrupole deformation ratio beta-2-n/beta-2-c = 0.84 +/- 0.08. This result conflicts with the predictions of the best available Hartree-Fock models.
