Absence of quantum interference in liquids experimental evidence

2 Absence of quantum interference in liquids experimental evidence 

Kao and Cutler (1988) found in Se ej x between x=0.1 and 0.2, where the metallic approximation is valid, that a is proportional to F and thus, if N( )oc 1/2, to [N( f)]2, in agreement with our hypothesis for the materials discussed above (provided that the tail to N( ) does not affect N(E) for these values of x). 

Further evidence is given in Section 5.5 for solutions of alkali metals in ammonia. 

as regards the Knight shift, only this fraction of the nuclei will feel the resultant field. Those that do will be acted on by a strong field that is independent of H but increase as a increases. Thus the NMR line should show a splitting AH independent of Hy but increasing rapidly as c0—c increases. The two lines will be of comparable intensity when (1) approaches unity. Since 2N(E)fi2 is the Pauli susceptibility x, this occurs when 

If a-1 is greater than the distance between centres, as it must be near the transition, then this should occur for fields much smaller than those required to saturate the moments. The expected behaviour is shown in Fig. 10.8.
