Protons and neutrons in the atomic nucleus move in shells analogous to the electronic shell structures of atoms. The nuclear shell structure varies as a result of changes in the nuclear mean field with the number of neutronsNand protonsZ, and these variations can be probed by measuring the mas...
The fast-atom bombardment (FAB) mass spectra, in 3-nitrobenzyl alcohol (NOBA) matrices, of the cyanamide or organonitrile complexes trans-[FeH(NCR)(dppe)2][BF4] [1; R=NH2, NMe2, NEt2 or NC(NH2)2; dppe=Ph2PCH2CH2PPh2] and cis- or trans-[ReCl(NCR)(dppe)2] (2; R=aryl...
X-ray bursts are among the brightest stellar objects frequently observed in the sky by space-based telescopes. A type-I X-ray burst is understood as a violent thermonuclear explosion on the surface of a neutron star, accreting matter from a companion sta
Atomic number and mass number are always whole numbers because they are obtained by counting whole objects (protons, neutrons, and electrons). The sum of the mass number and the atomic number for an atom (A-Z) corresponds to the total number of subatomic particles present in the atom. The...
