Electron-nucleus interaction probabilities are increased by the
increase in the near nucleus electron density. This premise may sound
far fetched, but the chemical-nuclear relationship is no longer
easily dismissed because it has been firmly established with regard
to electron capture. 18 A nearly one percent difference in half life
occurs simply due to the difference between electron wave functions
for 7Be atoms inside C60 instead of Be metal. Further, the half life
for 7Be atoms inside C60 was found to decrease upon cooling, and this
was correlated to electron density at the Be nucleus.19
