A method of calculating high-spin states of nuclei within the cranked Nilsson-Strutinsky framework is presented and discussed in some detail. With this method, various high-spin features of nuclei are studied, such as shape coexistence, shape changes, band crossings and band terminations. Nuclei with different mass numbers such as 106Pd, 118Te, 158Yb and 187Au are used to exemplify the formalism. Comparisons are made with observed discrete high-spin states in 160, 165, 168Yb, 168Hf, 171Ta and 130Ce. 相似文献

We prove Wolff inequalities for multi-parameter Riesz potentials and Wolff potentials in Lebesque spaces L p (R d ) and multi-parameter Morrey spaces ${L^p_\lambda (R^d)}$ , where ${R^d=R^{n_1} \times R^{n_2} \times \cdots \times R^{n_k},\, \lambda = (\lambda _1,\ldots ,\lambda _k})$ and 0?<?λ i ≤ n i , 1?≤ i ≤ k, in the dyadic case as well as in the non-dyadic (continuous) case. 相似文献

The cranked Nilsson-Strutinsky formalism is applied to the many-faceted spectrum of 16O. The deformation parameters ?, γ and ε4 are varied independently and many-particle-many-hole excitations are considered in the rotating system. Potential-energy surfaces are presented at different values of spin, parity and signature. Surprisingly good agreement is obtained when the different minima are compared with the measured states. Generally, it is observed that the more particles that are excited to higher shells, the larger becomes the intrinsic deformation. Rotational bands as well as pure p-h excitations, the latter sometimes constituting the termination of a rotational band, are identified. Additional high-spin states (I ? 12) are suggested. A microscopic analysis is performed of the rotational bands which emerge when 16O in its triaxial 4p-4h configuration rotates around each of its three principal axes. 相似文献
