Abstract :
Alpha particle spectra in coincidence both with normal deformed (ND) and superdeformed (SD) bands of 150Tb have been measured using the reaction 120Sn(37Cl,α3n) at 187 MeV bombarding energy. A clear difference is observed between the two spectra, that in coincidence with the SD states being shifted to lower energies. This effect is understood in terms of different angular momentum regions from which the ND and SD states orginate. The standard statistical model fails to describe the angular momentum dependence of the alpha particle energies.
