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 a novel two-step procedure for the calculation of
the continuum limit of these wave functions.
