Partial Half-Life of 22Na: Ec & β+ Emission

AI Thread Summary
The discussion centers on calculating the partial half-lives of 22Na for decay via electron capture (Ec) and beta-plus (β+) emission. The user initially calculates the overall half-life of 22Na as 2.602 years and derives a decay constant (λ) of 0.266 yr-1. However, they express confusion regarding the percentage contributions of each decay type. Another participant points out that this information can be easily found in decay tables or through online searches. The conversation highlights the importance of understanding the decay mechanisms and their respective proportions for accurate analysis.

Homework Statement


What are the partial half of 22Na for decay by
a)Ec
b) β+ emission

Homework Equations


λ=ln2/T1/2

The Attempt at a Solution


this what I do
T1/2 =2.602 Yr

λ=ln2/2.602

λ=0.266 yr-1what is the difference between
a)Ec
b) β+ emission
there is no Percentage of each decay type.!

Of course there is. You can look it up in any table of decays or find it online by doing a quick Google search!
 
Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'
(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
