Resumen
The electron capture to positron emission ratios for allowed Gamow-Teller transitions from the decay of22Na and65Zn were measured. The values ɛ/β⁺=0.1128±0.0057 and K/β⁺= 31.3±2.0 were obtained for ²²Na and ⁶⁵Zn, respectively. A detailed comparison with previous data is made. Theoretical ratios were calculated using the most recent Fermi and Coulomb functions. It was found an excellent agreement between our experimental data and the theoretical results evaluated without including contributions due to induced interactions. Facultad de Ciencias Exactas
