Average M shell fluorescence yields ((w) over bar(M)) and the total M shell
x-ray fluorescence (MXRF) cross-sections (sigma(M)(x)) at 6 keV were calcu
lated theoretically for elements,vith 29 less than or equal to Z less than
or equal to 100. These calculated values were compared with other experimen
tal and theoretical values. Copyright (C) 1999 John Wiley & Sons, Ltd.
