We present the study of K∗0 in Au+Au collisions at √SNN = 19.6 GeV from RHIC BES-II. The ratio of resonanse to non-resonance (K∗0/K) is shown as function of centrality and center-of-mass energy, which implies the dominance of hadronic re-scattering over regeneration in central A+A collisions. The lower limit of hadronic phase lifetime (tkin − tchem) is also reported using a toy model ansartz. The results are compared with previous RHIC and LHC measurements.
