The method of correlation femtoscopy makes it possible to estimate the parameters of the particle-emitting region (radius of emission region, $R$, and correlation strength, $\lambda$). Measurement of femtoscopic radius dependence on transverse momentum of particle pairs, $k_T$, is an important tool for studying the dynamics of the emission process [1].
This work is devoted to the study of momentum correlations of identical pions produced in Au+Au collisions at $\sqrt{s_{NN}}$ = 3 GeV using the UrQMD (Ultrarelativistic Quantum Molecular Dynamics) model [2, 3]. Three-dimensional femtoscopic analysis was performed as a function of $k_T$, rapidity and collision centrality. Physical implications will be discussed.
