Super, THANKS ! Resonance makes a lot of sense to me in this case. A further question: You say unbound. I am guessing that is more than just not stable or is the term 'unbound' specific to all nuclei that have half lives ?

Thanks for the equation, that helps alot. Still a little confused on width of the nucleus. I understand that we might be happier dealing in Mev, and Kev rather than zepto seconds. Similarly, reduced Planck or Dirac have units of (energy*time), so the equation results in time. My thought on...

Yes, I have a certain amount of quantum mechanics background. Worked with it through various solid state classes, learning, work experiences.

I am not sure I understand what you mean by width of the nucleus -link ? How can I convert from this energy unit to time or time to this energy unit if I need a constant reference across isotopes ? I appreciate any advice / direction.

I have been looking at half-life of various isotopes and many of the tables / information I am finding is giving energies (MeV, KeV) for certain half lifes. This does not make sense to me, am I missing something ? For example : http://ie.lbl.gov/toi/listnuc.asp?sql=&A1=5&A2=5 5Li and 5He give...

Hi Doug, Thanks for the leads. The first two seem like the standard "chart" version. I think i need to play with them a bit more to see if I can get a table view as I want to load this information into a program. The Wikipedia one is the right format, I might cut and past them together. But...

I am looking for tabular view of all isotopes (*.xls, *.csv, *.ods , ... ). Preferably with as much information as possible - half life, mean life, decay constant, specific activity, ... Any thoughts on where this might exist. I am wondering about correlations between stability and different...

Hi all , Just signed up. Looking forward to discussions. Also posing some questions
