Abstract :
The very neutron-deficient isotope 94Ag was produced at the GSI on-line mass separator by using the reaction 58Ni(40Ca, p3n). The β-decay properties of 94Ag were studied by detecting for the first time β-delayed γ rays and β–γ–γ coincidences. Both the population of excited levels in the daughter nucleus 94Pd and the β-decay half-life of 94Ag were investigated. The major part of the feeding was assigned to the decay of an Iπ=(7+) isomer with a half-life of (0.36±0.03) s. A weak β-decay branch was found to populate high-spin levels in the 94Pd daughter with I⩾18. It is tentatively assigned to the decay of a high-spin parent state in 94Ag with I⩾17 and a half-life (0.3±0.2) s. The measured β-decay properties as well as the level structure of 94Ag and 94Pd are discussed in comparison with shell-model predictions.
