“…Supporting this conclusion, a similar R(t) amplitude to the one observed in the present work was reported in Ref. [39]. In that case, 66 Ga was implanted into a nonferromagnetic Cu foil, using an external field to induce the nuclear precession.…”

“…The amplitude of R(t) reported in Ref. [39] corresponds to full alignment from the reaction, and agrees with the amplitudes observed for iron hosts here. (There is a very weak and slow damping evident in Ref.…”

“…The initial R(t) amplitudes observed in the present work are similar to each other, and to those previously reported for a variety of impurities, with the same or similar mass, in iron, gadolinium, and copper [7,18,39]. Higher temperature measurements of B hf are taken from Refs.…”

“…(There is a very weak and slow damping evident in Ref. [39] that might stem from weak hyperfine interactions or from incomplete background subtraction in the formation of the R(t) function, but it is irrelevant as concerns the initial amplitude of the R(t) function that is of interest here. )…”
