Abstract: (APS)

We report the measurement of

K^{* 0}

meson at midrapidity (

| y | <

1.0) in

Au + Au

collisions at

\sqrt{s_{N N}} = 7.7

, 11.5, 14.5, 19.6, 27, and 39 GeV collected by the STAR experiment during the Relativistic Heavy Ion Collider (RHIC) beam energy scan program. The transverse momentum spectra, yield, and average transverse momentum of

K^{* 0}

are presented as functions of collision centrality and beam energy. The

K^{* 0} / K

yield ratios are presented for different collision centrality intervals and beam energies. The

K^{* 0} / K

ratio in heavy-ion collisions are observed to be smaller than that in small-system collisions (

e + e

and

p + p

). The

K^{* 0} / K

ratio follows a similar centrality dependence to that observed in previous RHIC and Large Hadron Collider measurements. The data favor the scenario of the dominance of hadronic rescattering over regeneration for

K^{* 0}

production in the hadronic phase of the medium.
