How to set the EPR-spectrometer into the regime of registration of absorption signal?

We are working with EPR spectrometer Radio-pan H102. We use ruby in the role of reference. If we determine well regime of registration of absorption signal for ruby, then for studied sample, we...

What is the role of dislocations in the xrd pattern?

Hi there! In diamond sample with dislocations we saw lateral lines of line(220). These lines are not symmetry by intensity ( for three lines- lateral-central-lateral: 1012-2292-602) and position...
