چکیده
We systematically determine ground-state and saddle-point shapes masses for 1305 heavy superheavy nuclei with $Z=98-126$ $N=134-192$, including odd-$A$ odd-odd systems. From these, we derive static fission barrier heights, one- two-nucleon separation energies, $Q_\alpha$ values g.s. to g.s transitions. Our study is performed within the microscopic-macroscopic method deformed Woods-Saxon single-particle potential Yukawa-plus-exponential macroscopic energy taken as smooth part. use parameters of model that were fitted previously even-even nuclei. For systems odd numbers protons, neutrons, or both, a standard BCS blocking. Ground-state energies are found by minimization over seven axially-symmetric deformations. A search saddle-points was using "imaginary water flow" in three consecutive stages, five- (for nonaxial shapes) seven-dimensional reflection-asymmetric deformation spaces. The results collected two main tables. Calculated mass excess, nucleon separation- total, macroscopic(normalized at spherical shape) shell corrections deformations given each nucleus \mbox{Table 1}. 2} contains calculated properties configurations heights. In \mbox{Tables 3-7}, ground-state, inner outer superdeformed secondary minima characteristics 75 actinide nuclei, from Ac Cf, which experimental estimates heights known. These an additional test our model.

Stability of the Heaviest Nuclei
Spontaneous–fission half–lives (T SF 1/2 ) of the heaviest even–even nuclei are evaluated and compared with their alpha–decay mode. Calculations of T SF 1/2 are performed in the dynamical way with potential energy obtained by the macroscopic–microscopic method and the inertia tensor obtained by the cranking approximation. The alpha– decay half–lives (Tα 1/2) are calculated for the same region o...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Entrance-channel potentials in nucleus-nucleus collisions, relevant for the synthesis of superheavy elements, are systematically studied within a semi-microscopic approach, where microscopic nuclear densities of the colliding spherical or deformed nuclei are used in semi-classical expressions of the energydensity functional. From experimental data on fusion windows evidence is found that the ex...
