In conditions of 4{pi}-geometry, the production of {delta}{sup ++} and {delta}{sup 0} resonances in {pi}{sup -}+ {sup 12}C interactions at 40 GeV/c was investigated for the first time. The masses and widths of resonances were obtained from an analysis of the experimental and background invariant mass distributions of p{pi}{sup {+-}} pairs. The fractions of charged pions coming from {delta}{sup ++} and {delta}{sup 0} decay as well as the inclusive cross-section of {delta}{sup ++} and {delta}{sup 0} production were determined. The results obtained were compared to the recent results on {delta}(1232) production in {sup 4}He +C and C+C collisions at 4.2 GeV/c per nucleon, and Ni+Ni and Au+Au collisions at energies between 1 and 2A GeV.
