The decays of Tl/sup 199/ to Hg/sup 199/ and Au/sup 199/ to Hg/sup 199/ have b een examined using gamma-ray coincidence spectrometry and angular correlation techniques. The level order as well as level spins of Hg/sup 199/ deduced from this study support the recent work of Jung and Svedberg. The branching ratios of the electron capture transitions from Tl/sup 199 to six levels in Hl/sup 199/ have also been determined, Particular emphasis was placed on obtaining the empirical parameters of importance to the measurement of the magnetic moment of the 158-kev first excited state in Hg/sup 199/ as well as to the interpretation of the state as one member of a doublet resulting from coupling the 1/2- ground state with the 2/sup +/ core excitation. This interpretation, due to de-Shalit, implies the interrelations of some of the magnetic moments and lifetimes of the states involved. This study supports such an interpretation. (auth)
