In a bubble chamber experiment with BEBC the spin alignment parameter η= 1 2 (2ϱ 00 − ϱ 11 − ϱ −1−1 ) is measured for ϱ0 mesons produced in deep inelastic charged-current antineutrino and neutrono interactions on neon. In the current fragmentation region η is found to be η v =0.48±0.27 ( stat. )±0.15 ( syst. ) for v Ne and ηv=0.12±0.20 (stat.)±0.10 (syst.) for vNe interactions
