I am a PhD student in GJU S&T, I am working on rare earth doped single crystals. I have the same problem for calculating J-O intensity parameter. actually JOES calculate only Eu doped materials & relic not available so what I can do .pls help me . Thankyou

first, calculate fexp by applying the standard formula. calculate the area of each absorption curve using Origin software.
then calculate fcal, using the value of reduced matrix elements of each transition. follow paper of WT Carnall.
then equate both fexp and fcal, you will get a set of equations (depending upon the number of transitions selected for calculations) with JO parameters and reduced elements on LHS and (Number)*10-20 on RHS.
Try to solve these equations. omega 2, omega 4 and omega 6 are variables in equations.
follow physics and chemistry of rare earth volume 25.
