Multiple Quantum Transitions in Atomic Beam Magnetic Resonance

Abstract

<p>The problem of multiple quantum transitions between the magnetic sub-levels of an atomic ground state hyperfine multiplet has been investigated both experimentally and theoretically. Special emphasis has been paid to the behaviour of these transitions as the magnetic sub-levels of the hyperfine multiplet depart from equal level spacing</p> <p>The experiments performed determine the power dependence of the multiple quantum transitions of Na23. These experiments led to the establishment of a technique of determining transition multiplicity.</p> <p>Expressions are also developed which permit the calculation of transition probabilities for arbitrary values of multiplicity, r . f. amplitude and degree of inequality of level spacing.</p>
