β- and γ-spectroscopy study of ¹¹⁹Pd and ¹¹⁹Ag

RADIOACTIVITY ^119,119mPd(β^-)[from ²⁵³U(p, F), E=25 MeV]; measured Eβ, Iβ, Eγ, Iγ, βγ-coin, γγ-coin, γγ∓coin; deduced β-branching ratios, logft, T_1/2. ²⁵²Cf(SF); measured Eγ, Iγ, γ(θ), γγγ-coin. ¹¹⁹Pd; levels, J, π, T_1/2 for ground state and proposed 11/2^- isomer. ¹¹⁹Ag; deduced levels, J, π, multipolarities, ICC, δ, structure of rotational band. Discovered 2 separate bands in ¹¹⁹Ag possibly feeded by 2 different β-decaying states in ¹¹⁹Pd. Systematics of low-energy excitations in odd-A isotopes of Rh, Ag, In, and selected low-energy levels in odd-A nuclei of cadmium (¹⁰⁹Cd, ¹¹¹Cd, ¹¹³Cd, ¹¹⁵Cd, ¹¹⁷Cd, ¹¹⁹Cd, ¹²¹Cd, ¹²³Cd), the isotones of palladium. Isotopes of ¹¹⁹Pd were separated and purified using IGISOL technique and JYFLTRAP Penning trap. Gammas from ²⁵²Cf spontaneous fission were measured with Gammasphere array at ANL.
