- 	Mass absorption coefficient of doped sample
 
Mass absorption coefficient of doped sample, mD* , is the sum of the ratios of the doped fraction xJD , with absorption coefficient mJ*,  and the remaining fraction (1- xJD) with absorption coefficient m*
mD*  = m* (1 - xJD ) + mJ* xJD
Now substitute these values for (xJ)D and mD* into …(1)
(IiJ)D 	= KiJ [xJ (1-xJD) + xJD]  /  [m* (1- xJD) + mJ xJD ]
	= KiJ [xJ (1-xJD) + xJD]  /  [m* {1+ xJD(mJ* - m* ) / m* }]
