First observation of atomic levels for the element fermium (Z=100).
The atomic level structure of the element fermium was investigated for the first time using a sample of 2.7x10(10) atoms of the isotope 255Fm with a half-life of 20.1 h. The atoms were evaporated from a filament and stored in the argon buffer gas of an optical cell. Atomic levels were sought by the method of resonance ionization spectroscopy using an excimer-dye-laser combination. Two atomic le...
متن کاملA suggested periodic table up to Z≤ 172, based on Dirac-Fock calculations on atoms and ions.
Extended Average Level (EAL) Dirac-Fock calculations on atoms and ions agree with earlier work in that a rough shell-filling order for the elements 119-172 is 8s < 5g≤ 8p(1/2) < 6f < 7d < 9s < 9p(1/2) < 8p(3/2). The present Periodic Table develops further that of Fricke, Greiner and Waber [Theor. Chim. Acta 1971, 21, 235] by formally assigning the elements 121-164 to (nlj) slots on the basis of...
متن کامل0 Symmetry - Unrestricted Skyrme - Hartree - Fock - Bogoliubov Calculations for Exotic Shapes in N = Z Nuclei from 64 Ge to 84
By performing fully 3D symmetry-unrestricted Skyrme-Hartree-FockBogoliubov calculations, we discuss shape coexistence and possibility of exotic deformations simultaneously breaking the reflection and axial symmetries in proton-rich N = Z nuclei: Ge, Se, Kr, Sr, Zr and Mo. Results of calculation indicate that the oblate ground state of Se is extremely soft against the Y33 triangular deformation,...

متن کاملStatic Class Elements for Object-Z
Static variables and methods are part of almost every modern object-oriented programming language. Static elements are for instance indispensable for certain kinds of design patterns applied during programming. Object-oriented specification formalisms on the other hand lack such concepts. This can prevent writing formal specifications close to the actual implementation, and can thus hamper a re...
