Experimental and shell-model study of the beta decay of 43Ti

The mirror nuclei in the f 7/2 shell offer an excellent possibility for systematic studies of various nuclear properties. These nuclei decay by a strong mixed Fermi and Gamow-Teller decay to the ground state of the daughter nucleus and by weak Gamow-Teller decays to the excited states. The accurate determination of the Gamow-Teller strength provides a sensitive test for the nuclear shell-model calculations.
