Level After Decay of Radioactive Isotope

  1. Aug 27, 2014 #1
    Hello!

    So I have an issue with determining the probability of a daughter isotope's nucleus being on a certain level after decay from an unstable parent isotope's nucleus on another level. For example: I have a Co-60 nucleus and it decays to a Ni-60 nucleus by B- emission. If the parent Co-60 nucleus was excited at X keV and the daughter nucleus is excited at Y keV, how do I figure out the probability of this transition occurring. Or perhaps where do I find this data?

    Thanks!

    Much of the work has already been accomplished by various national and international laboratories.

    If one were to determine decay levels from scratch, one would have to do detailed gamma spectroscopy and determine the strengths or intensities of various gamma peaks.
