A class of integrable spin Calogero-Moser systems. Part II. Exact solvability

In a previous paper, we introduce a class of integrable spin Calogero-Moser systems associated with the classical dynamical r-matrices with spectral parameter. Here the main purpose is to give explicit solutions of several factorization problems associated with infinite-dimensional Lie groupoids which will allow us to write down the solutions of these integrable models.
