dc.descriptionWe consider the large-N Calogero model in the \h\ collective-field approach based on the $1/N$ expansion. The Bogomol'nyi limit appears and the corresponding equation for the semiclassical configuration gives the correct ground-state energy. Using the method of the orthogonal polynomial we find the excitation spectrum of density fluctuations around the semiclassical solution for any value of the statistical parametar $ł$. The wave functions of the excited states are explicitly constructed as a product of Hermite polynomials in terms of the collective modes.The two-point correlation function is calculated as a series expansion in $1/ρ$ for any intermediate statistics.
