摘要：

At low degree, the semiclassical analysis suggests an expansion in powers of (l+1/2)(2), as an alternative to the standard high-frequency asymptotic expansion in powers of(1/omega)(2). The first two terms in the resulted eigenfrequency equation describe the large and the small frequency separations. Small separations are interpreted as a measure of the forward scattering amplitude.
