The Investigation of Superdeformed Bands Using Segmented FFT Analysis
Abstract
The Fast Fourier Transform band-locator technique( C.V. Hampton, W.A. Olivier, Wm.C. McHarris, ``A Search Technique for γ-Ray Bands Using Segmented Fourier Analysis'', presented at the Joint APS/AAPT Annual Meeting, Indianapolis, IN, May 2-5, 1996.) that had been developed for γ-ray spectra is employed as a tool to investigate superdeformed (SD) bands. The search technique is simple: Conversion of the band into frequency space provides a pattern, segments of which act as a template to be extracted from the frequency spectrum of the original data set. The presence of these segmented band frequencies provides useful information in identifying and analyzing the band. The method was performed on published SD band data. The surprising results show an unusual phase shift that we believe will have significant impact on the search for SD bands.
