Transient NMRON of brute force oriented 110mAgAg

A novel technique involving electrodeposition has been used to prepare an elemental silver specimen wherein radioactive 110mAg probe nuclei are confined to a surface layer of approximately 0.1 μm depth. This specimen was then brute force oriented in a field of 8 T and the continuous wave (CW) nuclear magnetic resonance of oriented nuclei (NMRON) spectrum showed an integrated destruction of some 58%. Moreover the transient NMRON techniques of single and modulated adiabatic passage were successfully applied, resulting in a determination of the electric quadrupole interaction strength at the 110mAg site in polycrystalline silver of P/h=+0.74(5) kHz with a FWHM of ΔP/h=0.75(8) kHz. The resulting mode electric field gradient is VZZ=+1.87(23)x1018 V m-1. Analysis of the single passage data provides an estimate for the nuclear spin lattice relaxation constant in silver at 8 T of Ck=1.63(3) s.K. (orig.)
