OSTI ID:6263965
The indirect superhyperfine interaction (ISHFI) between impurity electrons and host nuclei in Van Vleck paramagnets is induced by the large magnetic polarizability of the ground singlet electronic state of the Van Vleck cation. ISHFI effects were observed on neutral, spin S = 1/2 impurities for the first time. They appear in the EPR spectrum of Na-Y zeolite, partially ion-exchanged with /sup 165/Ho/sup 3 +/, which has been dehydrated and ..gamma..-irradiated.
