 \n\nThere is a method that allows directly measuring the spatio-temporal e
 xtent of the region where hadrons are emitted and the parameters of the nu
 clear-nuclear interaction\, called femtoscopic correlation [1]. In heavy-i
 on collisions\, femtoscopy is an important tool for studying the geometric
  and dynamic characteristics of the emission region.\nTwo-particle momentu
 m correlations of identical particles in nuclear-nuclear collisions make i
 t possible to extract femtoscopic parameters (radii of emission region\, $
 R$\, and correlation strength\, $\\lambda$) [2]. Reaction dynamic is refle
 cted in the femtoscopic radii dependence on pair transverse momentum\, $k_
 T$.\nThis work is devoted to the study of two-particle momentum correlatio
 ns of identical pions produced in collisions of gold nuclei in the STAR ex
 periment at the RHIC at $\\sqrt{s_{NN}} = 3$ GeV. The extracted three-dime
 nsional femtoscopic radii ($R_{out}$\, $R_{side}$\, $R_{long}$) are measur
 ed as a function of collision centrality and transverse momentum of the pa
 irs.\n\n\nReferences:\n[1] Podgoretsky M.I. Interference correlations of i
