摘要：

Nine superdeformed bands in several nuclei of the mass-190 region all have transitions of the same or equivalent energies to within an average of about 1 keV almost identical. Furthermore, it is found that transitions of the same energy do not always connect levels of the same spin, indicating noncollective angular momentum alignments that are all very nearly integers (0, 1Latin small letter h with stroke, or 2Latin small letter h with stroke). Possible explanations involving pseudospin are discussed. © 1990 The American Physical Society.
