A measurement of the g factor and lifetime of the 5.106 MeV 2- state of 14N

The g factor of the 5.106 MeV 2- state of 14N has been measured by the recoil-distance technique. The perturbation of the nuclear alignment in one-electron ions was observed reaction in a 3He-implanted target. From the observed hyperfine frequency, the nuclear g factor was deduced to be /g/ = 0.66(4). The lifetimes of the 5.106 MeV 2-state (tau)sub(m)(2-) = 6.2(4)ps) and the 5.832 MeV 3-state (tausub(m)(3-) = 13.7(11)ps) were measured, also by the recoil-distance technique, using the reaction 12C(3He,p)14N*. The former result is significantly different from the published value. (author)
