TRANSIENT NMRON OF BRUTE FORCE ORIENTED (AGAG)-AG-110M

A novel technique involving electrodeposition has been used to prepare an elemental silver specimen wherein radioactive Ag-110m probe nuclei are confined to a surface layer of approximately 0.1 mum length. This specimen was then brute force oriented in a field of 8T and the continuous wave (CW) nuclear magnetic resonance on 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 Ag-110m site in polycrystalline silver of P/h=+0.74(5)kHz with a FWHM Of DELTAP/h=0.75(8)kHz. The resulting mode electric field gradient is V(zz)=+1.87(23)x10(18)Vm-1. Analysis of the single passage data provides an estimate for the nuclear spin lattice relaxation constant in silver at 8T Of C(k)=1.6(3)s.K.
