摘要: Identical particle correlations at fixed multiplicity are considered by means of quantum canonical ensemble finite systems. We calculate one-particle momentum spectra and two-particle Bose-Einstein correlation functions in the ideal gas using a recurrence relation for partition function. Within such model we investigate validity thermal Wick's theorem its applicability decomposition distribution The dependence parameters on average pair is also investigated. Specifically, present analytical formulas that allow one to estimate effect suppressing system. results can be used femtoscopy analysis $A+A$ $p+p$ collisions with selected (fixed) multiplicity.
