✦ Synopsis

Following the approach of Jones, Low, and Young, a generalized O(2,l) expansion is developed for amplitudes that have a power bounded growth asymptotically. The expansion, set up in an 0(1, 1) basis, holds in a new kinematical region, where all the incoming and outgoing clusters have space-like 0(2, 1) momenta. 299

In a paper published by Langer in 1949 it was shown that the eigenvalues X of a rotating harmonic oscillator, containing a parameter oi < 1, are given by the formula X = v + O(a In cc), where v is an integer. In the present paper it is shown that Langer's estimate is too rough; the correct formula i
