  Transverse momentum spectra of proton, deuteron and triton in gold-gold
(Au-Au) collisions at 54.4 GeV are analyzed in different centrality bins by the
blast wave model with Tsallis statistics. The model results are approximately
in agreement with the experimental data measured by STAR Collaboration in
special transverse momentum ranges. We extracted the kinetic freeze out
temperature, transverse flow velocity and freeze out volume from the transverse
momentum spectra of the particles. It is observed that the kinetic freeze out
temperature is increasing from central to peripheral collisions. However the
transverse flow velocity and freeze out volume decrease from central to
peripheral collisions. The present work reveals the mass dependent kinetic
freeze out and volume differential freeze out scenario in collisions at STAR
Collaboration. In addition, the parameter q characterizes the degree of
non-equilibrium of the produced system, and it increase from central to
peripheral collisions and increase.
