Query: Coherent distributions for the rigid rotator   This work presents Wigner-type quasiprobability distributions for the rigid
rotator which become, in the limit h=0, coherent solutions of the classical
Liouville equation known as the "action waves" of Hamilton-Jacobi theory. The
results are consistent with the usual quantization of the intrinsic angular
momentum, but for the expectation value of the Hamiltonian, a finite "zero
point" energy term is obtained. It is shown that during the time when a
quasiprobability distribution evolves according to the Liouville equation, the
related quantum wave function should satisfy the time-dependent Schroedinger
equation.
