The multipartite entangled state n p χ χ χ ,..., , , 3 2 for the total momentum and relative coordinates of n particles is constructed. The corresponding quantum mechanical operator with respect to the classical transformation p p e 1 λ → , i i i e χ χ λ → , n i ,..., 2 = , in the state n p χ χ χ ,..., , , 3 2 is investigated.
