Abstract The average multiplicities of charged hadrons and of π+, π− and π0 mesons, produced in $$\bar v$$ Ne and νNe charged current interactions in the forward and backward hemispheres of theW ±-nucleon center of mass system, are studied with data from BEBC. The dependence of the multiplicities on the hadronic mass (W) and on the laboratory rapidity (y Lab) and the energy fraction (z) of the pion is also investigated. Special care is taken to determine the π0 multiplicity accurately. The ratio of average π multiplicities $$\frac{{2\left\langle {n_{\pi ^O } } \right\rangle }}{{[\left\langle {n_{\pi ^ + } } \right\rangle + \left\langle {n_{\pi ^ - } } \right\rangle ]}}$$ is consistent with 1. In the backward hemisphere $$\left\langle {n_{\pi ^O } } \right\rangle $$ is positively correlated with the charged multiplicity. This correlation, as well as differences in multiplicities between $$\mathop v\limits^{( - )} $$ and $$\mathop v\limits^{( - )} $$ , $$\mathop v\limits^{( - )} $$ scattering, is attributed to reinteractions inside the neon nucleus of the hadrons produced in the initial $$\mathop v\limits^{( - )} $$ interaction.
