Abstract
We present an analytical Fourier transform method (AFT), to calculate semiclassical eigenvalues of multidimensional systems in the regular r egime. The AFT method is compared with some previous semiclassical tec hniques which make use of the fast Fourier transform (FFT). It is show n that the AFT method combines the best properties of those FFT proced ures: accuracy, stability and simplicity.
