Résumé : The β-strength function of104Cd is studied in the β+/EC decay of mass-separated104In. The determination of the β+ feeding and the β+/β+EC ratio is the result of the simultaneous measurement of beta and gamma rays in one semiconductor beta-spectrometer. Information on the strength function near the QEC value is obtained from the detection of high-energy γ rays. The total observed β strength amounts up to 10% of the Extreme Single-Particle Shell Model value. A strong enhancement in the β+/EC feeding to a group of levels around 5.6 MeV shows the influence of the Gamow-Teller Resonance. © 1990 Springer-Verlag.
