Abstract
The beta-decay of Ti-40 and Ca-35 have been studied at the LISE3 spectromet er at GANIL. The decay schemes were deduced from the observed beta-delayed proton and gamma emission of Ti-40 and Ca-35 into the ground and first exci ted states of Ca-39 and Ar-34, respectively. The Gamow-Teller strength func tion B(GT) of the Ti-40 beta-decay, extracted from the beta-decay branching ratios and the precisely measured Ti-40 half-life, provides for the first time an experimental calibration of the neutrino detection efficiency for t he ICARUS solar neutrino detector.
