Spectrum of an Elliptic Free Fermionic Corner Transfer Matrix Hamiltonian
(20K, LaTeX)

ABSTRACT.  The eigenvalues of the Corner Transfer Matrix Hamiltonian
associated to the elliptic R matrix of the eight vertex free
fermion model are computed in the anisotropic case for magnetic
field smaller than the critical value.
An argument based on generating functions is given, and
the results are checked numerically. The spectrum consists of
equally spaced levels.
