The parametrizations of the Fermi momentum vs. mass number (a) and separation energy vs. parameter\(\xi =Z/A^{1/3}\)(b) according to Eqs. (2). The data points are taken from Refs. [81,82,83]. The filled bands indicate the\(1\sigma \)uncertainties of the interpolations. The ...
mass number and atomic number E.g.1 Oxygen: O 16 8 E.g.2 Oxygen - 16 E.g.3 O-16 These values are given on the periodic table. For now, round the mass # to a whole number. These numbers tell you a lot about atoms. # of protons = # of electrons = atomic number # of ...

mass of the biopolymer, the compounds of our present study were explicitly tailored to avoid this: the number of ionizable Trp chromophores increases in proportion with the polymer length and the simulations show that for all tested circumstances they are arranged abundantly on the molecular surface...
Solution aerosols are injected into an inductlvety coupled argon plasma (ICP) to generate a relatively high number density of positive ions derived from elemental constituents. A small fraction of these ions is extracted through a sampling orifice into a differentially pumped vacuum system housing an...
