  By using a variant of the quantum inverse scattering method, commutation
relations between all elements of the quantum monodromy matrix of bosonic
Massive Thirring (BMT) model are obtained. Using those relations, the quantum
integrability of BMT model is established and the S-matrix of two-body
scattering between the corresponding quasi particles has been obtained. It is
observed that for some special values of the coupling constant, there exists an
upper bound on the number of quasi-particles that can form a quantum-soliton
state of BMT model. We also calculate the binding energy for a N-soliton state
of quantum BMT model.
