Homework Help Overview

The discussion revolves around identifying possible ground-state beta decays for the isobaric mass chain A=141, focusing on various decay modes such as beta minus, beta plus, and electron capture, as well as their classifications like allowed or first-forbidden.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are exploring the types of beta decays possible for A=141 nuclei and questioning the initial steps needed to analyze the decay modes based on mass conservation principles.

Discussion Status

The discussion is ongoing, with participants providing hints and guidance regarding the use of the NNDC website and considerations related to the odd number of nucleons in A=141. There is a mix of attempts to clarify the problem and expressions of urgency regarding the deadline.

Contextual Notes

Participants note the importance of the deadline and the implications of having an odd number of nucleons in the mass chain, which may affect the decay modes available for consideration.

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.)

The Attempt at a Solution


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! :rolleyes:

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.
