Mass number, in nuclear physics, the sum of the numbers of protons and neutrons present in the nucleus of an atom. The mass number is commonly cited in distinguishing among the isotopes of an element, all of which have the same atomic number (number of p
However, the conditions that need to be satisfied by the rows and columns of a unitary matrix, as well as the requirement that the determinant of the matrix should be +1, reduce the number to eight independent real parameters. These eight parameters lead to eight generators of the SU(3) ...
research collaborations for the discovery of the element with atomic number 112 at Gesellschaft f眉r Schwerionenforschung (GSI) share in the fulfillment of those criteria. A synopsis of Z = 112 experiments and related efforts is presented. A subsequent report will address identification of higher-...

over the years following the war quite a number of empty 44 gallon drums similar to the one pictured below were found up and down along the beach and under the water not far Pendills Creek. The tops of the drums were stamped with a number of German words including the date 1943. The ...
Discovery of the Element with Atomic Number 112 Priority for the discovery of the element with atomic number 112 has been assigned, in accordance with the agreed criteria, to Gesellschaft für Schwerionenforschung (GSI) (Center for Heavy Ion Research) in Darmstadt, Germany. The discovery evidence...
Synthesis of a New Element with Atomic Number Z=117 The discovery of a new chemical element with atomic number Z=117 is reported. The isotopes (293)117 and (294)117 were produced in fusion reactions between ... TO Yu,FS Abdullin,PD Bailey,... - 《Physical Review Letters》...
The problem is that the computational requirements are so high that systems that can be studied this way are limited to a small number of atoms (see Section 7.4). Different approaches can be followed to simplify this problem, dealing with different The character of the conductance modes in a ...
Low-dimensional materials have a limited number of atoms in certain dimensions. Because of this structural feature, their properties are particularly sensitive to atom number, arrangement, position, and so on. High-entropy alloys necessitate the atomic-scale combination of multimetallic components. ...
