Abstract :
We find from our measurements that the decay rate of 7Be implanted in Au is lower than that implanted in Al2O3 by a relatively large amount (0.72±0.07)%. This result and others have been analyzed quantitatively using the linear muffin-tin orbital (LMTO) method and Hartreeʹs calculations. Our results are important for accurately extracting the nuclear matrix element of the astrophysically significant 7Be + e−→ 7Li + ν reaction.
