Abstract
- 40 Ti β decay was studied at GANIL using the LISE3 spectrometer. A decay scheme was deduced from twenty-one observed β-delayed proton transitions feeding the ground and first excited states of 39 Ca. The 40 Ti half-life was found to be 51.7(6) ms. These results imply that the ICARUS 40 Ar detector has an effective absorption cross section for 8 B solar neutrinos of 14.5(4) × 10 −43 cm 2 ; 73% of the total cross section arises from Gamow-Teller transitions that were neglected in early estimates of the ICARUS efficiency.
