TL;DR: In this article, the problem of the very different E2 decay rates from the two-quasineutron K = 6 isomers in the N = 104 isotones Er, Yb, Hf, and W is investigated using the triaxial projected shell model with inclusion of multi-quaiparticle configurations.
Abstract: The problem of the very different E2 decay rates from the two-quasineutron K = 6 isomers in the N = 104 isotones Er, Yb, Hf, and W is investigated using the triaxial projected shell model with inclusion of multi-quasiparticle configurations. It is demonstrated that the highly K-forbidden transition from the 6 isomer to the ground-state band is sensitive to mixing with the 6 state of the γ-vibrational band. Thus the inter-band transitions, and lifetimes, depend on the relative position of the γ-band and the isomeric state in each isotone. © 2013 IOP Publishing Ltd.

TL;DR: In this article, a realistic density-dependent nucleon-nucleon (NN) interaction with finite-range exchange part which produces the nuclear matter saturation curve and the energy dependence of the nucleonnucleus optical model potential is used to calculate the preformation probability, S α, of α-decay from different isotones with neutron numbers.

TL;DR: In this paper, the authors introduced two new variants of weakly contraction mappings for two and three maps in metric spaces and derived a couple of common fixed point theorems for T-strictly weakly isotone increasing mappings and relatively weakly increasing mapping in partially ordered complete metric spaces.
Abstract: In this paper we introduce two new variants of weakly contraction mappings for two and three maps in metric spaces and derive a couple of common fixed point theorems for T-strictly weakly isotone increasing mappings and relatively weakly increasing mapping in partially ordered complete metric spaces. Our results are illustrated by giving some examples.

TL;DR: The direct product of two formal fuzzy contexts is focused on and conditions under which a bond can be obtained as an intent of the product are shown.
Abstract: L-bonds represent relationships between formal contexts. We study properties of these intercontextual structures w.r.t. isotone concept- forming operators in fuzzy setting. We also focus on the direct product of two formal fuzzy contexts and show conditions under which a bond can be obtained as an intent of the product. In addition, we show that the previously studied properties of their antitone counterparts can be easily derived from the present results.

01 Jan 2013TL;DR: The category CRL-ChuCors is introduced, incorporating residuation to the underlying complete lattice L, specifically, on the ba- sis of a residuation-preserving isotone Galois connection.
Abstract: We continue our study of the general notion of L-Chu cor- respondence by introducing the category CRL-ChuCors incorporating residuation to the underlying complete lattice L, specifically, on the ba- sis of a residuation-preserving isotone Galois connection . Then, the L-bonds are generalized within this same framework, and its structure is related to that of the extent of a suitably defined -direct product.

TL;DR: In this article, the ground state of even-even nuclei with extreme neutron excess that are remote from the known neutron drip line (NDL) is calculated based on Hartree-Fock method with Skyrme forces SkM*, SkI2, Sly4, Ska) with allowance for axial deformation and the BCS pairing approximation.
Abstract: The properties of the ground state of even-even nuclei with extreme neutron excess that are remote from the known neutron drip line (NDL) are calculated. The calculations are based on the Hartree-Fock method with Skyrme forces SkM*, SkI2, Sly4, Ska) with allowance for axial deformation and the BCS pairing approximation. It is shown that the isotone chain at the neutron number N = 126 beyond the NDL forms a peninsula of nuclei that are stable with respect to the emission of one neutron (PNS). The neutron and proton density distributions of the PNS nuclei have spherical symmetry. A mechanism for restoring the stability of nuclei beyond the NDL is discussed. The obtained results are compared with those from Hartree-Fock-Bogoliubov calculations for long isotope chains of Zr and Pd up to the NDL.

TL;DR: In this article, the authors established new xed point theorems for a set-valued operator satisfying generalized contractive condition in a partially ordered complete metric space and showed that the use of order can be crucial.
Abstract: In the present work we establish some new xed point theorems for a set-valued operator satisfying generalized contractive condition in a partially ordered complete metric space. Thereafter we present common xed point results for a pair of weakly isotone increasing set-valued mappings. Finally, some examples are given to illustrate the usability of our results, also showing that the use of order can be crucial.
