Abstract

Forward-angle differential cross sections for the Ho165(π+,π0)165Er(IAS) reaction have been measured at Tπ=98.0, 163.2, and 228.3 MeV in the angular range &≲14°. The shapes of the angular distributions at 98.0 and 163.2 MeV are compared to predictions arising from the strong absorption model of pion single-charge exchange scattering. Extrapolated 0° cross sections are compared with trends previously established with mostly spherical and near-spherical nuclei. The measurement demonstrates the possibility of using the (π+,π0) reaction for studying neutron density deformations in oriented Ho165.
