Abstract.
The \(\beta\)-decay properties of the neutron-deficient nuclei 25Si and 26P have been investigated at the GANIL/LISE3 facility by means of charged-particle and \(\gamma\)-ray spectroscopy. The decay schemes obtained and the Gamow-Teller strength distributions are compared to shell-model calculations based on the USD interaction. B(GT) values derived from the absolute measurement of the \(\beta\)-decay branching ratios give rise to a quenching factor of the Gamow-Teller strength of 0.6. A precise half-life of \(43.7\: (6)\) ms was determined for 26P, the \(\beta\)-(2)p decay mode of which is described.
