Alignment-to-orientation conversion and nuclear quadrupole resonance

arXiv:physics/0302084 · doi:10.1016/S0009-2614(03)01327-7

Abstract

The role of alignment-to-orientation conversion (AOC) in nuclear quadrupole resonance (NQR) is discussed. AOC is shown to be the mechanism responsible for the appearance of macroscopic orientation in a sample originally lacking any global polarization. Parallels are drawn between NQR and AOC in atomic physics.
