Platzman plot

Figure 6 A Platzman plot of the ratio of the secondary electron cross sections for ionization of N2 by electrons to the comparable Rutherford cross sections. Q is the energy loss, Q = W+B, and is equivalent to the parameter E used in the text. (From Ref. 44.)...

Figure 11 A Platzman plot, the ratio of the experimental single differential cross section for electron emission from helium by 1-MeV protons to the corresponding Rutherford cross sections plotted as a function of RjE. The experimental cross sections are from Ref. 54 and the differential oscillator strength is taken from Ref. 43.

Figure 1 (a) Single differential cross sections (in the units of 10 cm /eV) as a function of energy loss W (=Ii+s), for the production of cations from electron impact ionization of SiH at constant electron impact energy of 100 eV. (b) Same as (a) but at E=200 eV. (c) The solid lines show the trends of the calculated ratios of cross sections in Platzman plot Y(W) in half energy ran at 100 and 200 eV.
