where one of its isotopes,211At, is remarkably well suited for targeted radionuclide therapy of cancer. With the At−anion being involved in many aspects of current astatine labeling protocols, the knowledge
"Remember that each orbital has two electrons and the number of orbitals at an energy level depends on the first two quantum numbers." What does this mean? How does an atom try to fill its valence shell? The configuration (2s)2(2s*)2(2py)1(2px)1 is the molecular orbital d...
Thirty years of relativistic self-consistent field theory for molecules: relativistic and electron correlation effects for atomic and molecular systems of transactinide superheavy elements up to ekaplutonium E126 with g-atomic spinors in the ground state configuration Journal Theoretical Chemistry Accounts Vo...
the electron beam can be focused using electromagnetic lenses. In one embodiment, the SEM configuration also provides a system to scan the electron beam over an area of the substrate. In one embodiment, such as a SEM embodiment, an imaging system is further included. In one embodiment, an im...
What is the electron configuration for an atom in an excited state? How can one balance chemical equations with given oxidation numbers? If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of prot...
A great motivation for this investigation is the remarkable agreement between the recent first ever EA measurement of the highly radioactive At atom [3] and various theoretical EAs [4]. The authors of [3] used the coupled-cluster method, while [4] employed a multiconfiguration Dirac Hartree-...
