Observation of Non Yrast States in Barium Nuclei Following Isomeric β-Decay with the Osiris Cube Detector Array

摘要: There is a large variety of different quadrupole shapes being observed in the investigation nuclear deformation. In Koln we have worked on number nuclei with particularly interesting shapes. We will mention just few recent results. doubly magic 146Gd nucleus spherical shell model states up to 16 MeV been [1]. same two superdeformed bands, which extend an excitation energy 32 MeV, were found by OSIRIS collaboration [2] [3]. This extreme case shape coexistence. A similar phenomenon “doubly magic” 114Sn new prolate band negative parity related deformed Amsterdam positive and coexists vibrations [4]. J. Eberth has spectrometer coexistence oblate bands 69 Se. These are well developed deformation β = 0.3 was determined [5].
