If it loses an electron Ce-148 becomes Pr-148, or in the way you write it 148/59 Pr.

Use this equation to find the rate constant:

ln(2) = kt{1/2}

k = ln(2)/t{1/2} = 0.69321/48 s = ...

Solution Summary

Beta decay is investigated. The solution discusses what is the product formed and how much of the product is formed.
