Two nuclear isomers were studied using in-beam gamma-ray spectroscopic techniques in conjunction with the reactions ('204)Hg(t,2n(gamma))('205)Tl and ('204)Hg(t,p(gamma))('206)Hg. The isomeric state in ('205)Tl was determined to have J('(pi)) = 25/2('+) with the major configuration (('206)Pb7('-) x h(,11/2)('-1)). The mean lifetime and gyromagnetic ratio for the state were determined to be (tau)(,m) = 3.7 (+OR-) 0.3 (mu)sec and g = 0.544 (+OR-) 0.008, respectively. Using this g-factor and previously measured g-factor for the ('206)Pb7('-) state, a g-factor, g = 1.264 (+OR-) 0.027, was deduced for an h(,11/2) proton state. For the nucleus ('206)Hg a new isomeric state was seen at 2.102 MeV excitation energy. This state was determined to have J('(pi)) = 5('-) with a mean lifetime (tau)(,m) = 3.1 (+OR-) 0.3 (mu)sec and the gyromagnetic ratio was measured to be 1.09 (+OR-) 0.01. The major configuration of the isomeric state if {h(,11/2)('-1)s(,1/2)('-1)} and using the value for g(h(,11/2)) determined from ('205)Tl, the g-factor for a 3s(,1/2) proton state was determined. / Source: Dissertation Abstracts International, Volume: 43-04, Section: B, page: 1098. / Thesis (Ph.D.)--The Florida State University, 1982.
