The problem of orbital collapse of the 5g and 6f electrons in atoms of superheavy elements (SHEs) is considered. Previously, the presence of the orbital collapse was established for the 4f and 5f elements of the periodic table. Because of the large centrifugal term for the f and g electrons, the effective radial potential has two wells, one narrow and deep and the other wide but shallow.
Abstract For superheavy elements with atomic numbers 120≤Z≤170, the concept of the ground-state configuration is being reexamined. To this end, relativistic calculations of the electronic structure of the low-lying levels are carried out by means of the Dirac-Fock and configuration-interaction methods. The magnetic and retardation parts of the Breit interaction as well as the QED effects are taken into account.
An unusual spatial pattern on the ocean surface was captured by thermal airborne swaths taken across a strong sea surface temperature front at the North Wall of the Gulf Stream. The thermal pattern on the cold side of the front resembles a staircase consisting of tens of steps, each up to ?200 m wide and up to ?0.3?C warm. The steps are well organized, clearly separated by sharp temperature gradients, mostly parallel and aligned with the primary front.
