Production of low-pT (soft) hadronic particles in high energy
collisions constitutes a significant corner of special interests
and problems, as the perturbative quantum chromodynamics
does not work in this region. We have probed here into the nature
of the light particle production in two symmetric nuclear
collisions at two neighbouring energies with the help of two
non-standard models. The results are found to be in good agreement
with data. Despite this, as the models applied here are not
intended to provide deep insights into the actual physical
processes involved in such collisions, the phenomenological
bounds and constraints which cannot be remedied for the present
continue to exist.
