Semi-empirical mass formula

From the semi-empirical mass formula Eq. (2.2), neglecting the last two terms, the gain in B.E. for a nucleus splitting into two equal fragments is... [Pg.40]

These competing forces helped form the semi-empirical mass formula (SEMF) shown in the following equation ... [Pg.55]

Beta stability is thought to be known reasonably well, with use being made of the semi-empirical mass formula. Johansson et al. think it unlikely that an error of more than one or two units of N for a given Z will result from the prediction of the beta-stability line. Electron capture in superheavy elements has been considered by Morovic and by Grumann, Morovic, and Greiner. ... [Pg.42]

In the following first example the liquid ozone concentration and the OH-radical concentration are calculated with semi-empirical formula from the mass balance for ozone (Laplanche et al., 1993). For ozonation in a bubble column, with or without hydrogen peroxide addition, they developed a computer program to predict the removal of micropollutants. The main influencing parameters, i. e. pH, TOC, U V absorbance at 254 nm (SAC254), inorganic carbon, alkalinity and concentration of the micropollutant M are taken into consideration. [Pg.132]

Semi-empirical molecular orbital calculations using the INDO/S method have been carried out for organoscandium complexes of the general formula Cp 2ScX (X = C1, I, Me, CH2Ph, NHPh).549 The utility of electrospray mass spectrometry for the characterization of air-sensitive organolanthanides and related species has been demonstrated.550 A wide variety of lanthanide complexes, including divalent and trivalent compounds, neutral and... [Pg.69]

Here the rate coefficient is in cm /mole sec, To and hco are given in degrees Kelvin, and the reduced mass of colliding particles, /r, is in atomic mass units. A semi-empirical formula for VT-relaxation time (in seconds) as a function of pressme (in atmospheres) was proposed by Milliken White (1963) ... [Pg.70]
