Abstract

The β\beta-decay properties of the neutron-deficient nuclei 25^{25}Si and 26^{26}P have been investigated at the GANIL/LISE3 facility by means of charged-particle and γ\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 β\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 26^{26}P, the β\beta- (2)p decay mode of which is described.
