A procedure that relies on analyzing the angle between the momenta of the proton and the pion originating from CTa interaction at a projectile momentum of 4.2 GeV/c per nucleon was used to investigate for the first time the production of {Delta}{sup 0} and {Delta}{sup ++} resonances in such interactions and to determine their parameters. The criterion of stability in the parameter a characterizing the background contribution was presented for the first time and was used to reconstruct the mass distributions of {Delta}{sup 0} and {Delta}{sup ++} resonances. The contributions of {Delta}{sup 0}- and {Delta}{sup ++}-resonance decays to the production of charged pions were estimated. The results of this study are compared with similar data obtained by using the analogous procedure for {Delta}{sup 0} and {Delta}{sup ++} resonances produced on carbon nuclei in CC and {sup 4}HeC collisions at a projectile momentum of 4.2 GeV/c per nucleon and in {pi}{sup -12}C interactions at a projectile momentum of 40 GeV/c.
