Lorentz shape signal

Curves 2 (Ei E) and 5 (Ei L E) in Fig. 4.15 refer to the uoj Jj/T 1 scale, in which the excited state Hanle effect manifests itself (the ground state Hanle effect is already fully developed and does not manifest itself in this scale). The signal is of Lorentz shape ... 

Use the same series of data and follow the same procedure as before to try out the Lorentz-Gauss convert window type. There is one single parameter LB available to adjust the window. Set the initial value to LB = 0, increment and decrement its value in small steps and inspect the shape of the window using the interactive mode. Note that for LB > 0 the shape of the window is similar to the exponential window (signal-to-noise improvement) whereas for LB < 0 the window shape is similar to the sine-bell squared window. Try out a few values to enhance the signal-to-noise ratio and to improve the resolution, store the results and compare the spectra using the multiple display. 

Lorentz curves with a tail function for the asymmetry of the XPS signals for these transition elements. These sets were kept constant in position, shape and size relative to each other. The XPS spectrum of an actual specimen was described with a least-square fit by variation of the size of the appropriate standard sets [36]. Various standards were prepared and measured for a subsequent data analysis of actual specimens. Only some few examples are mentioned here. Pure metal standards are Ar-sputter cleaned specimens. Fe(III) oxide corresponds to a thick passive layer formed at the positive end of the passive range. For Fe(II), a passive layer formed on Fe5Cr is reduced in 1 M NaOH at ca. = -1.0 V (SHE) [12]. For NiO, oxide grown at 1000 °C on pure Ni in air was used as a standard. For Ni(III)oxyhydroxide, NiOOH was deposited by oxidation of Ni2+ from weakly alkaline solution or formed...
