Measurement of the Cotton-Mouton effect in nitrogen, oxygen, carbon dioxide, argon, and krypton with the Q & A apparatus

摘要

Experiments for vacuum birefringence and vacuum dichroism have been set upwith high-finesse high magnetic experimental apparatuses, which seem to beideal for small gaseous Cotton-Mouton effect (CME) measurements. PVLASCollaboration has measured CMEs in krypton, xenon and neon at the wavelength of1064 nm. In this Letter, we report on our measurement of CMEs in nitrogen,oxygen, carbon dioxide, argon, and krypton at the same wavelength in a magneticfield B = 2.3 T at pressure P = 0.5-300 Torr and temperature T = 295-298 K. Ourresults agree with the PVLAS results in the common cases.
