The nucleus that decays is called the parent nucleus, and the nucleus that is produced is called the daughter nucleus. In general, multiple levels are possible in the daughter nucleus, and the ratio of levels to each level is called the branching ratio. … *Some of the terminology explanations that mention "parent nucleus" are listed below.
