Abstract
The decay rate of 7Be electron capture (EC) was measured in C60 and Be metal with a reference method. The halflives of 7Be endohedral C60 (7Be@C60) and 7Be in Be metal (Be metal (7Be) ) were found to be 52.65±0.04 and 53.25±0.04 days, respectively. This amounts to a 1.13% difference in the EC-decay half-life between 7Be@C60 and Be meta (7Be). The result is a reflection of the different electron wave-functions for 7Be inside C60 compared to when 7Be is in a Be metal. Here, the magnitude of the average charge-transfer from the L (2s) electrons of the 7Be atom plays an important role in such variation in the decay constant in the environments.
