110. Define the photoelectric probability. p. 343. Ch 111. Use FIG 7.30 to explain how the absorption edge parameter j for the K edge of Pb will be decided. Mass attenuation coefficient for photoelectric effect /(cm2/g) electric mass attent of j and Pj we plot in Fig. 7.30 the photofrom 1keV to 100krV. coefficient / for lead in the photon energy range with associated subedges and covers the K,L, and M absorption edges K absorption edge (7.32cm2/displays the high and low / values for the the three L subshells and five /g and 1.56cm2/g, respectively) as well as for edge parameters j for the K. energy ranges. The table also provides a summary of data required for determination of absorption edge parameters j for lead. Row (4) gives the K, L, and M subshell binding energies; row (5) the K,L, and M fluorescence yields; rows (6) and (7) the high and low / values, respectively, at the K shell and the L and M subshell absorption edges. The table also provides the photoelectric probabilities Pj calculated with (7.148) for various photon energy regions covering photon energies from EB(M1)=3.9keV to h=. As discussed above, for subshells j with binding energy EB(j) exceeding the photon energy h, the photoelectric probability Pj is zero, i.e., for h
