Title:  Towards Explicit States in a Sigma Model

Abstract:  In the CP1 sigma model, fractional instantons
nonpertubatively generate a mass gap.  To understand how they do it,
we wish to explicitly calculate the ground state and first excited
state wave functions using the known equivalence to the XXX spin
chain.   We describe two novel techniques which will allow, for the
first time, the continuum limit of these wave functions to be
calculated.
