Microwave ultrasonic paramagnetic resonance of the Cr²⁺ion in magnesium oxide

Laser with a wavefront-reversing mirror andQswitching by stimulated Brillouin backscattering

“…No changes were detected, though we had hoped to produce V + ions, which, being isoelectronic with Cr2+, might give a strong a.p.r. absorption (Fletcher et al 1966). …”
