True . . . almost, Rajini. Instead of eV, take h-bar in MeV,
since Michael Dayah’s periodic table lists the values in MeVs.
Otherwise mean lifetime will come out in megaseconds, Ms. (Ms = million seconds)
Thank you Rajini.
Hello Rajini.
Yes, you are right. After converting MeV to Joules, I divided the values for ‘decay width’ into h-bar and got the ‘mean lifetime’ in seconds. So now I understand the mystery. Your last post clinched it for me. Thank you Rajini.
That periodic table at http://www.ptable.com/ is...
Thank you very much Astronuc.
I have a good ideal what ‘mean lifetime’ is now, a term new to me. The Wikipedia link you gave contained a good discussion about exponential decay and explained well the new term.
There is something strange though. I first encountered the term ‘decay width’ on...
Thank you Rajini.
No, I havn't got it. I looked up 'Lorentzian function' on the internet and I see it involves a whole lot of math. I like math, but I was hoping for a more 'intuitive' definition for decay width. Or maybe better, words combined with equations to tie them to the concept. That...
Thank you very much to HotCells and Astronuc.
With above 2 posts and links, I think I can start to better understand 'decay width' now.
My question was originally related to radionuclides, but I like the particles too.
Thanks.
Thank you for your help above.
In regard to those links above, an equation is good but that does not really tell me what 'resonance width' is. The 'definition' at that link is so short, it can hardly be a 'discussion'.
May be that the sort of definition I was looking for is wrong for this...
I have looked for a definition of 'decay width' on the internet and could only find articles that use the term, no definition. I first saw the term on a periodic table of elements showing information about different radioactive isotopes and their decay modes. Is 'resonance width' a synonym...
