What Ground-State Beta Decays Are Possible for Isobaric Mass Chain A=141?

[cmyers152]

Homework Statement

Consider the isobaric mass chain A=141. Using the NNDC website, determine what types of ground-state beta decays are possible for different elements within this chain (beta minus, beta plus, EC, etc.) as well as the nature (allowed, first-forbidden, etc.)

I have no idea how to even start this and its due at 9am

What does the website tell you about A=141 nuclei? What are their masses?
The possibility of beta decay modes is just a matter of conservation of energy. If the decay products have less total mass it is possible, otherwise it is not.

The world has many time zones, by the way.

thanks for the sass and not helping...

I would expect my questions to be very useful as guideline how to find the answer.

Did you not see the "by 9AM" part? Harrumph!

CMyers, one other hint to keep in mind is that A=141 has an odd number of nucleons. That will give you a different answer than if it had an even number.
