In this research we have obtained plots of many single isotope alpha decays
to different states of the daughter nucleus.
286) says that the alpha decay
of bismuth-209 was not listed in any reference table.
Consider the first kind of alpha decay
. When we say with Belot that this particle that is actually [Beta]1 could have been [Beta]2 there is at least one clear sense in which it comes out true: [Beta]1 could have been called '[Beta]2' rather than '[Beta]1'.
This allowed them to measure the photons in connection with the new element's alpha decay
During a routine check for contamination in their bolometers, which happen to be built around crystals containing bismuth, the team noticed an unexpected alpha decay
not listed in any reference tables.
