英文摘要	The transverse momentum spectra of triton with STAR Beam Energy Scan data from Au+Au collisions at root N-SS = 7.7, 11.5, 14.5, 19.6, 27, 39, 62.4, 200 GeV in the centrality classes 0 - 10%, 10 - 20%, 20 - 40% and 40 - 80% are reported. The centrality dependence of the coalescence parameter B-3 of triton and the collision energy dependence of the relative neutron density fluctuation are then calculated. The results indicate that the B-3 decreases from peripheral to central collisions and the neutron density fluctuation shows a non-monotonic collision energy dependence with a peak around collision energy of 20-30 GeV. In addition, we report details about the reconstruction method of H-3(Lambda) via H-3(Lambda) -> 4 He-3 + pi(-) and H-3(Lambda) -> + p + pi(-) using high statistics data in Au+Au collisions at root S-NN = 200 GeV collected in 2014 and 2016 with the Heavy Flavor Tracker.
