  We study the dynamics of multiwormhole configurations within the framework of
the Euclidean Polyakov approach to string theory, incorporating a modification
to the Hamiltonian which makes it impossible to interpret the Coleman Alpha
parameters of the effective interactions as a quantum field on superspace,
reducible to an infinite tower of fields on space-time. We obtain a Planckian
probability measure for the Alphas that allows $\frac{1}{2}\alpha^{2}$ to be
interpreted as the energy of the quanta of a radiation field on superspace
whose values may still fix the coupling constants.
