We analyzed the transverse momentum spectra of proton, deuteron and triton inBoron-Boron (B-B), Oxygen-Oxygen (O-O), and Calcium-Calcium (Ca-Ca) centralcollisions, as well as in several centrality bins in Gold-Gold (Au-Au)collisions at 39 GeV by using the blast wave model with Tsallis statistics. Thebulk properties in terms of kinetic freeze-out temperature, transverse flowvelocity and kinetic freeze-out volume are extracted from the model by theleast square method. We observed that with increasing the rest mass of theparticle, the kinetic freeze-out temperature becomes larger, while transverseflow velocity and the kinetic freeze-out volume reduces. These parameters arealso found to depend on the size of the system. Larger the size of the system,the larger they are. Furthermore, the kinetic freeze-out temperature inperipheral Au-Au collisions is close to the central O-O collisions. We alsoobserved that the above parameters depend on the centrality, and they decreasefrom central to peripheral collisions. Besides, we also extracted theentropy-index parameter $q$, and the parameter $N_0$ which shows themultiplicity. Both of them depend on the size of interacting the system, restmass of the particle and centrality. Both $q$ and $N_0$ are larger for lighterparticles, and the former is smaller for large systems while the latter islarger, and the former decrease with increasing centrality while the latterincrease.
