  The 6-vertex model with appropriately chosen alternating inhomogeneities
gives the so-called light-cone lattice regularization of the sine-Gordon
(Massive-Thirring) model. In this integrable lattice model we consider pure
hole states above the antiferromagnetic vacuum and express the norm of
Bethe-wave functions in terms of the hole's positions and the counting-function
of the state under consideration. In the light-cone regularized picture pure
hole states correspond to pure soliton (fermion) states of the sine-Gordon
(massive Thirring) model. Hence, we analyze the continuum limit of our new
formula for the norm of the Bethe-wave functions. We show, that the physically
most relevant determinant part of our formula can be expanded in the large
volume limit and turns out to be proportional to the Gaudin-determinant of pure
soliton states in the sine-Gordon model defined in finite volume.
