A search was made among ν μ charged current events collected in the NOMAD experiment for the reaction: ν μ +N→μ − +D ★+ + hadrons ↪ D 0 +π + ↪ K − +π + . A high purity D ★+ sample composed of 35 events was extracted. The D ★+ yield in ν μ charged current interactions was measured to be T =(0.79±0.17(stat.)±0.10(syst.))%. The mean fraction of the hadronic jet energy taken by the D ★+ is 0.67±0.02(stat.)±0.02(syst.). The distributions of the fragmentation variables z, P T 2 and x F for D ★+ are also presented.

MOMENTUM SPECTRA IN THE WINDOW P=0.1-6.0 HAVE BEEN FITTED BY THE FORMULA: (1/N)*D(N)/D(P)=CONST(Q=1)*EXP(-SLOPE(Q=1)*P)+CONST(Q=2)*EXP (-SLOPE(Q=2)*P).
