Abstract

In a series of measurements performed at the IGISOL facility at the Accelerator Laboratory of the University of Jyväskylä, the half-lives of 26Si, 29P, 30,31S, 42Ti and 62Ga were measured with high precision. These half-lives are important ingredients for tests of the weak-interaction standard model and allow, together with other experimental inputs and theoretical correction terms, the determination of the vector coupling constant of the weak interaction. The IGISOL method used in Jyväkylä is an ideal tool for these measurements as it allows to access all elements without distinction of their chemical properties.
