Looking for excited state gamma emission data on everything?

Click For Summary

Discussion Overview

The discussion revolves around the search for a comprehensive database on gamma emission from excited states of isotopes, specifically focusing on non-decay gamma emissions resulting from various nuclear reactions such as non-elastic collisions and fusion/fission processes.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests a database for gamma emission data from excited states of isotopes for software development.
  • Several participants provide links to existing databases focused on gamma decay schemes, but these do not meet the specific needs outlined by the original poster.
  • Another participant clarifies that they are looking for gamma emissions from reactions, such as non-elastic collisions and nuclear transmutations, rather than standard decay schemes.
  • Examples of reactions are provided to illustrate the type of data being sought, emphasizing the need for information on gamma emissions resulting from excited states of specific isotopes.
  • A participant shares a link to a resource that may contain relevant data for isotopes in a specific mass range.
  • Another participant finds and shares a link to a database that might contain the desired information.

Areas of Agreement / Disagreement

Participants generally agree on the need for specific gamma emission data, but there is no consensus on whether the provided resources meet the requirements, as the focus on non-decay emissions remains contested.

Contextual Notes

The discussion highlights limitations in existing databases regarding the specific type of gamma emission data requested, and there are unresolved questions about the completeness and applicability of the resources shared.

Hey guys, I am looking for a database on gamma emission from the first few excited states of known isotopes for a piece of software we are putting together. Any format is fine.

Thanks!

Thank you gleem, unfortunately what we need is non decay gamma emission from things like non elastic collisions, product emission from fusion/fission reactions, etc..

Basically the gamma specs for all nuclides going from the excited states to ground states of each nucleus.

You want the gamma decay scheme right? for which nuclei?

Not the decay schemes, but more like from the products of reactions like this:

Si28+n->Si28+n+gamma, where the gamma comes from the excited state of the Si28

or this:

O16+T->F18+n gamma, where the gamma comes from the excited state of the F18

Basically, each nucleus has a ground state, if it is excited to a higher state via an incoming particle in a non elastic collision like in the first example, or by an energetic nuclear transmutation (products have less mass than the reactants, and E=mc^2, therefore energy is evolved) as in the second example.
 
You mean like this for O16 if so see http://www.tunl.duke.edu/nucldata/ for nuclei from A=5 to 20.
