A correlation between the (/sup 6/Li,/sup 6/He) cross sections and the Gamow-Teller strength observed previously for other targets persists in the /sup 14/C(/sup 6/Li,/sup 6/He)/sup 14/N reaction. The total Gamow-Teller strength up to 12 MeV excitation is measured and we derive sum rules for the Gamow-Teller strength which depend on the LS configurations of the target state. The extracted LS configuration of the /sup 14/C ground state is in serious disagreement with shell model calculations. There are several inconsistencies within our understanding of the nuclear structure and transition strengths in these nuclei, part of which is attributable to mesonic currents. Constraints are also placed upon the (/sup 6/Li,/sup 6/He) reaction mechanism.
