Direct Spin Determination of On-Line-Separated Isotopes by Nuclear Orientation and Nuclear Magnetic Resonance

Abstract

Nuclear magnetic resonance of on-line-oriented nuclei is reported for the first time, in the cases of mass-separated $^{106}\mathrm{In}$, $^{108}\mathrm{In}$, and $^{104}\mathrm{Ag}$. Combination of the extracted $g$ factors with independent information on the magnetic-moment values leads to unambiguous spin assignment for the high-spin ground states of $^{106}\mathrm{In}$ and $^{108}\mathrm{In}$. The high-precision magnetic moments derived for these nuclei as well as the result on $^{104}\mathrm{Ag}$ point to strong discrepancies from the additivity relation.
