decay chain

n.
A sequence of radioactive decay processes in which the decay of one element creates a new element that may itself be radioactive, and continuing until the sequence ends with stable, nonradioactive atoms.

Included in these changes are: new code architecture; incorporation of numerical solvers for the calculation of radioactive decay chains (including the in-growth of decay products during air transport and ground surface deposition); enhanced error messages; updated online help and a utility for migrating version 3 datasets, wind files and population files to version 4.
In the decay chains, both a previously unknown alpha-decay pathway in Db-270 (dubnium - element 105) and the new isotope Lr-266 (lawrencium - element 103) were identified.
Comparing the two decay chains, Hofmann says, will help researchers better understand the characteristics of superheavy elements.
