Hyperdeformed and megadeformed nuclei. Angular momentum projection is a superposition in the Euler space which lowers the total energy of the system. New spontaneous fission mode for Cf: Indication of hyperdeformed , Ba at scission. Only some nuclei can exist in superdeformed states. In nuclear physics a superdeformed nucleus is a nucleus that is very far from sphericalforming an ellipsoid with axes in ratios of approximately On the other hand, the major part of the contribution is indeed from many particles of the rest orbits although each individual may only contribute a little. For a higher -shell, it is evident that among all the orbitals, the down-sloping intruder orbitals with the highest are always occupied first. However, it is unfeasible in practice because of the unavoidable problem related to huge basis dimensions. However, it is often not the case in reality.


  • Pd is studied in detail, with a quantitative prediction on super- and hyper-​deformed spectra by the Projected Shell Model calculation.

    In nuclear physics a superdeformed nucleus is a nucleus that is very far from spherical, forming For the drawing style of anime and manga, see Super deformed. Even more deformed states () are called hyperdeformed.

    On the other hand, the major part of the contribution is indeed from many particles of the rest orbits although each individual may only contribute a little.

    New York: Springer, Google Scholar. Skip to main content. This relatively-simple model has been extensively tested in the past decade. However, it is unfeasible in practice because of the unavoidable problem related to huge basis dimensions.

    Thus, the present work has shown a picture of coexistence of three distinct deformation minima, corresponding to normal, super- and hyper-deformed shapes, in nuclei.

    As schematically shown in Fig. This relatively-simple model has been extensively tested in the past decade. The usual assumption of nuclear structure models is that a nucleus can be described as a set of interacting particles moving in an average potential.

    super and hyper) deformations without, preparing a. The super-deformed band of iS2Dy is analyzed as well as the structure of the hyper-deformed state predicted to appear in s at / = 60S I. to compute the shell corrections including the one obtained from a mean field calculation using the.
    In principle, the energies calculated with can have advantages over those with unprojected state in that the projection treats the states fully quantum-mechanically by collecting all the energy-degenerate mean-field states associated with the rotational symmetry.

    It can be seen that the pairing gaps decrease with spin as anticipated, which has been understood as a reduction in pairing correlation due to the rotational alignment. The first superdeformed states to be observed were the fission isomerslow-spin states of elements in the actinide and lanthanide series.

    Using a conventional shell model to study deformed, heavy nuclei is desirable. Spectroscopy of strongly deformed nuclei-from super to hyperdeformation. This is a preview of subscription content, log in to check access. As schematically shown in Fig.

    As we shall show in the present paper, three energy minima, which correspond to ND, SD, and HD shapes coexisting in one nucleus, can be formed in nuclei with neutron number around Search for hyperdeformation.

    2. To support the prediction, the PSM results for the two experimentally-known bands in Cd are also calculated by using the same calculation condition.

    3. However, it is unfeasible in practice because of the unavoidable problem related to huge basis dimensions.

    4. This means that our results suggest that a considerable amount of pairing correlation remains even in the highest spin states in the HD well.
