Popis: The production of $$\overline {D^0 } $$ -mesons on hydrogen and nuclear targets (carbon and aluminium) by (38–70) GeV neutrons has been analysed. The decay mode $$\overline {D^0 } \to K^ + \pi ^ - \pi ^ + \pi ^ - $$ has been studied. The longitudinalp L and transversep T momenta have been reconstructed and described by the forms (1−X F )N withN=2.3 −0.3 +0.2 and exp(-Bp T 2 ) withB=(1.3 −0.3 +0.2 ) (GeV/c)−2, respectively. In the sensitive kinematic region of (30≤p l ≤60) GeV/c $$(X_F \tilde > 0.5)$$ andp T ≤1GeV/c the cross sections are: σH2=(3.1±1.1)μb,σ c = (27.5±9.3) μb/C nucleus andσ Al =(49.6±16.3)μb/Al nucleus. The dependence of the $$\overline {D^0 } $$ -production cross section on the atomic weightA was parametrized by the power law form $$\sigma _A = K\sigma _{H_2 } A^\alpha $$ withK=1.5±0.8 andα=0.73±0.23.
