We report on a measurement of the differential and total cross sections of inclusive production of resonances in - nucleus collisions at 345 The cross section for inclusive production is about a factor of 5 below that of hyperons. The products of cross section and branching ratio for the observed channels and are lower by yet another order of magnitude. The and resonances show significantly harder xF and pt distributions than and hyperons. A comparison of the xF-distribution to PYTHIA and QGSM predictions provides only a partial agreement.
