The quadrupole coupling constant of the n(h~~~2 s~q'2) isomer in polycrystalline Hg at 225 K has . been measured by means of the perturbed angular distribution method. The result is e'Qq/h =136.5+3 MHz, from which we deduce eg =65+13 e fm' and an effective charge e,ff(m.h llg2) =(2.2+0.5)e.
The nuclear gyromagnetic ratio, spin parity, and lifetime of the Hg 2.102-MeV level have been measured to be g=1.09+0.01, J =5, and~=3.1+0.3 @sec, respectively.The level was populated via the~Hg(t, p) Hg reaction. The perturbed angular distribution technique was employed to measure g. Using known data, the spin gyromagnetic ratio for a proton in the 3s orbital has been deduced: g, (m;3s) =3.6+0.3. For the 1.068-MeV level, J =2+.
NUCLEAR REACTIONSHg(t, p), E& --16 MeV. For Hg (E"=2.102 MeV), measured~=3.1+0.3 @sec, g =1.09+0.01, and J =5 . For E"=1. 068 MeV, J =2+. Deduceg(m, '3s)=3.6+0.3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
