Mi. Gorenstein et Hg. Miller, ISOTOPIC ASYMMETRY AND COULOMB INTERACTIONS IN HEAVY-ION COLLISIONS, Physical review. C. Nuclear physics, 55(4), 1997, pp. 2002-2004
The effects of tile isotopic asymmetry of colliding nuclei and the Cou
lomb interactions are simultaneously considered for an equilibrated ha
dron gas produced in heavy-ion collisions, The asymmetry in the produc
tion of negative and positive pions which Is manifested In the differe
nces in the pi(-) and pi(+) multiplicities and in the shape of their m
omentum spectra is analyzed.
