We measured the π He4 and π 016 elastic scattering cross section for π~ mesons with momentum 1.02 GeV/c and the cross section for the excitation of the 3 (6.13 MeV) level of the O16 nucleus in the momentum-transfer interval 0.085-0.145 (GeV/c)2. It was found that the experimental values agree with the results of calculations by the Glauber theory. An indication of a possible difference between the neutron and proton form factors of the transition is obtained.
