Abstract

Excited states of Te-124 were measured with the transfer reactions Te-123(d,p) Te-124, Te-125(d,t) Te-124 and Sb-123(He-3,d) Te-124 and with the inelastic scattering reaction Te-124(p,p') Te-124 at the Tandem Accelerator in Munich. Levels were obtained up to 3.5 MeV with energy resolutions of 3-6 keV. The Te-124(gamma, gamma') Te-124 reaction was studied at the S-DALINAC accelerator in Darmstadt for bremsstrahlung endpoint energies E(0) = 3.5 and 5 MeV. The Te-123(n, gamma) Te-124 reaction with thermal neutrons was investigated in Riga and in Dubna including gamma-gamma coincidences. In Dubna the special method of sum coincidences was applied, analyzing the gamma-gamma cascades to the ground state and the first 2(+) level. Based on these experiments a level scheme was constructed with states up to 4.5 MeV which is assumed to becomplete up to 3 MeV for angular momenta J < 4HBAR. A quasiparticle-phonon model calculation with a configuration space of up to three-phonon coupling permits a good description for many of the low-energy states. Transition probabilities, E2/M1 mixing ratios and branching ratiosbetween these levels are generally well described. The quantitative reproduction indicates a two-phonon quadrupole-octupole coupled 1(-) structure of the states most strongly excited in the (gamma, gamma') reaction. The 2(-) member of the 2(1)(+) x 2(1)(+) x 3(1)(-) septuplet isidentified in the unusual decay cascade following thermal neutron capture. A candidate for a 2(+) state with mixed symmetry structure is proposed.
