I’d been studying radioactive decay in my courses, and Bill suggested we work together on calculating the lifetimes of new chemical elements, heavier than those in the known Periodic Table.

Ten come from radioactive decay in the detector materials, and in this particular energy range about three come from the sun’s main fusion reaction.

This explanation seemed very likely, for here and there were stumps of trees and decaying chips.
