I'm sorry, this is probably a pretty stupid question as I probably am just not understanding something basic about nuclear reactions. Can someone please help?
I am trying to understand what happens when Au-196 goes to Hg-196.
I am assuming it is something like:
[itex]Au^{196}_{79} \rightarrow Hg^{196}_{80} + e^- + \bar{\nu}_e + 0.686 MeV[/itex]
according to this table:
http://atom.kaeri.re.kr/cgi-bin/nuclide?nuc=Au196
What is confusing me is that it says the Au isotope is spin 2, and the table for Hg says the isotope is spin 0.
http://atom.kaeri.re.kr/cgi-bin/nuclide?nuc=Hg196
How is this possible?
Somehow the electron and neutrino must carry away some specific orbital angular momentum?
Also, what is the +/- they use in front of the spin numbers. How would a +2 be different than a -2?If I was to look at an electron capture:
[itex]Hg^{196}_{80} + e^- + energy \rightarrow Au^{196}_{79} + \nu_e[/itex]
Are there certain configurations/polarizations I can rule out due to the spin?
Does the negative beta decay energy it lists in the table mean this capture would require the electron have have at least ~ 4.4MeV of energy?
Any help understanding these tables would be great.
