The experimental transverse momentum distributions of negative pions produced in d{sup 12}C, {sup 4}He{sup 12}C, and {sup 12}C{sup 12}C collisions at 4.2 A GeV/c were analyzed in the framework of Hagedorn Thermodynamic Model. The spectral temperatures of {pi}{sup -} mesons as well as their relative contributions to the total multiplicity of {pi}{sup -} mesons were extracted from fitting the p{sub t} spectra by two-temperature Hagedorn function. The results were compared systematically with the earlier results obtained from analysis of non-invariant center-of-mass energy spectra of negative pions produced in the analyzed collisions.
