Full width half-max

Table 4.1 shows the composition of the three major elements in the gelatin films in terms of binding energy (BE), energy at full width half-max (FWHM) and mass concentration in percentage. From the data in the table, the compositions of O-ls, C-ls and N-ls across various percentages of GF show consistent readings of 24.58 0.77, 60.39 1.09 and 14.99 0.74 %, respectively. The values determined... 

If the diabatic coupling matrix element, He, is -independent, this d/dR matrix element between two adiabatic states must have a Lorentzian H-depen-dence with a full width at half maximum (FWHM) of 46. Evidently, the adiabatic electronic matrix element We(R) is not - independent but is strongly peaked near Rc- Its maximum value occurs at R = Rc and is equal to 1/46 = a/4He. Thus, if the diabatic matrix element He is large, the maximum value of the electronic matrix element between adiabatic curves is small. This is the situation where it is convenient to work with deperturbed adiabatic curves. On the contrary, if He is small, it becomes more convenient to start from diabatic curves. Table 3.5 compares the values of diabatic and adiabatic parameters. The deviation from the relation, We(i )max x FWHM = 1, is due to a slight dependence of He on R and a nonlinear variation of the energy difference between diabatic potentials. When We(R) is a relatively broad curve without a prominent maximum, the adiabatic approach is more convenient. When We (R) is sharply peaked, the diabatic picture is preferable. The first two cases in Table 3.5 would be more convenient to treat from an adiabatic point of view. The description of the last two cases would be simplest in terms of diabatic curves. The third case is intermediate between the two extreme cases and will be examined later (see Table 3.6). 

Figure 10.20 Synchrotron X-ray chemical nano-imaging reveals iron sub-cellular distribution. The synchrotron X-ray fluorescence nanoprobe endstation installed at ESRF was designed to provide a high flux hard X-ray beam of less than 90 nm size (FWHM, full width at half maximum). The intensity distribution in the focal plane is shown in (A) dopamine producing cells were exposed in vitro to 300 pM FeS04 during 24 h (B). Chemical element distributions, here potassium and iron, were recorded on distinct cellular areas such as cell bodies (C), neurite outgrowths, and distal ends (D). Iron was found in 200 nm structures in the cytosol, neurite outgrowths, and distal ends, but not in the nucleus. Iron-rich structures are not always resolved by the beam and clusters of larger dimension are also observed. Min max range bar units are arbitrary. Scale bars = 1 pm." 2007 PLoS ONE.
