Description
The spatial and temporal characteristics of particle emission source in high-energy collisions can be
measured by using two-particle femtoscopic correlations. These correlations arise due to quantum statistics,
Coulomb and strong final state interactions.
In this talk, we report on the measurement of like-sign meson femtoscopic correlations
produced in p+p, d+Au, Au+Au at top RHIC energy using Quantum Molecular Dynamics Model (UrQMD).
Three-dimensional correlation functions are constructed using the Bertsch-Pratt
parametrization of the two-particle relative momentum.
The correlation functions are studied in several transverse momentum ranges.
The emitting source radii of charged pions and kaons, $R_{out}$, $R_{side}$, $R_{long}$,
are obtained from Gaussian fit
to the correlation functions and compared to data from the STAR experiment.
