| Abstract: | Experimental results on the study of quasielastic reactionsv μ n→μ ? p and (bar v_u p to mu ^ + n) in the energy range 3–30 GeV are presented in this paper. Spark chamber detector with Al filters has been exposed to the wide-band neutrino and antineutrino beams at Serpukhov. Neutrino and antineutrino data have been used to reconstruct the behaviour of axial-vector form-factorF A (Q 2). We measured the total cross-sections as a function of energy. The parameterM A =(1.00±0.04) GeV/c2 has been determined under the assumption of the dipole parametrization and CVC hypothesis. Upper limit for the second class currents was estimated. |
