(Received April 14, 1969)
We study collective coordinates of rotational motion by means of canonical transformation. It is shown that our Hamiltonian is equivalent to that of Tamura, Nataf and Villars [T. Tamura, Nuovo Cim. 4 (1956), 1307; R. S. Nataf, Nucl. Phys. 2 (1957), 497; F. Villars, Annual Review of Nuclear Science (Annual Review Inc.) Vol. 7 (1957), p. 185]. Further investigation is carried out and it shows that a rotation-like collective motion is introduced besides rotation as a whole of a system and even in a spherically symmetric case we have rotational levels. Our interest is focussed on collective momenta rather than collective coordinates and they are generators of GL(3).
