The transverse momentum spectra of light nuclei (deuteron, triton and helion) produced in various centrality intervals Gold-Gold (Au-Au), Lead-Lead (Pb-Pb) proton-Lead (p-Pb) collisions, as well inelastic (INEL) proton-proton (pp) collisions are analyzed by the blast wave model with Boltzmann Gibbs statistics. results nearly agreement experimental data measured STAR ALICE Collaborations special ranges. We extracted bulk properties terms kinetic freezeout temperature, flow velocity volume. It is observed that deuteron anti-deuteron later than helion their anti-particles due to its smaller mass, while triton, anti-helion anti-triton at same time isospin symmetry higher energies. also earlier anti-nuclei large coalescence nucleons for compared anti-nuclei. volume decrease from central peripheral collisions. Furthermore, depends on mass particle which decreases increasing particle.
