In the AGS experiments, it was found that the coalescence parameter ([B.sub.2]) is of similar magnitude for both d and [bar.d] indicating similar freeze-out hyper surface of nucleons and antinucleons. Furthermore, the dependence of [B.sub.2] on collision energy and [p.sub.T] indicated that light nuclei production is strongly influenced by the source volume and transverse expansion profile of the system [58, 59].
Therefore, by applying G-parity transformation to nucleon potentials, one can obtain the corresponding potential for antinucleons. The result of G-parity transformation can be written as
