First, let's look at beta decay
|add proton to nickel yields copper, beta decays back to nickel|
|add 2nd proton to nickel yields copper, beta decays back to nickel again|
|add 3rd proton to nickel yields copper and back to nickel again|
|add 4th proton to nickel yields copper and back to nickel again|
The next proton yields stable copper.
Update: I had some company so I set this post aside for awhile. Now I am back. I'll finish this up in just a minute.
Okay, now I've loaded the ones I did for electron capture.
|Electron capture means it takes an electron close to the nucleus. This converts the proton into a neutron and releases energy. This happens with proton rich nuclei. The opposite occurs with neutron rich nucleii.|
|Just work through the same process as with beta decay, but don't know which one would occur before the other would. Perhaps the rule would be which takes the least energy.|
|In these pics, I am speculating that these reactions are feasible. If there is any info here that suggests otherwise, well, please excuse the amateurishness. I am after all, an amateur.|
|It looks like electron capture releases more energy.|
