The production of$\bar D$ mesons in neutroncarbon interactions at 40–70 GeV/c has been investigated. The$\bar D$ mesons were detected via the hadronic decay modes$\bar D^0\to K^{* + } (892)\pi ^ -$ andD−→K*+(892)π−π−. In the kinematical regionxF>0.5 andpT<1 GeV/c the following inclusive cross sections were measured:$\sigma _{\bar D^0 }= (28 \pm 14)\mu b$ and$\sigma _{D^ -}= (28 \pm 13)\mu b$ per carbon nucleus. The invariant longitudinal momentum spectra can be described by (1−x)N with$N_{\bar D^0 }= 1.1 \pm 0.5 \pm 0.4$ and$N_{D^ -}= 0.8 \pm 0.4 \pm 0.4$ The transverse momentum spectra were parametrized by exp (−BpT2) with$B_{\bar D^0 }= (1.2_{ - 0.9}^{ + 1.1} )({{GeV} \mathord{\left/ {\vphantom {{GeV} c}} \right. \kern-\nulldelimiterspace} c})^{ - 2} $ and$B_{D^ -}= (1.8_{ - 1.0}^{ + 1.3} )({{GeV} \mathord{\left/ {\vphantom {{GeV} c}} \right. \kern-\nulldelimiterspace} c})^{ - 2} $.

TheA-dependence of the polarization ofΛ0,s produced inclusively in neutron-nucleus interactions at a mean neutron momentum of about 40 GeV/c has been measured in an experiment performed using the BIS-2 spectrometer at the Serpukhov accelerator. Carbon, Aluminium and Copper targets were used. TheΛ0,s were produced in the kinematical region of 0.6<pT<1.3 GeV/c and 0.2<xF<0.9. Describing the polarization of theΛ0,s by ℘=a·A a value of (−0.15+0.07/−0.60) was obtained by a fit to our data.
