Level After Decay of Radioactive Isotope

[dlbi]

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.

Hi there!

That's an interesting question. The probability of a transition from the parent Co-60 nucleus to the daughter Ni-60 nucleus depends on a few factors, including the energy difference between the two levels, the nuclear spin and parity of the parent and daughter nuclei, and the type of decay (e.g. beta decay, alpha decay, etc.). These probabilities are typically calculated using quantum mechanics and are often referred to as transition probabilities or decay rates.

You can find data on these probabilities in nuclear physics textbooks or online databases such as the National Nuclear Data Center. However, keep in mind that these probabilities are theoretical and may not always match up exactly with experimental data. I hope this helps!
