Alpha Decay

Recommended Posts

Hi

 

Please could anyone advise the best way to show 7 successions of alpha decay on: 234

U

92

 

I know the answer is 206

Hg

80

 

Should I show it as 7 different stages eg. stage 1 234 230 4

U ---- Th + He

92 90 2

 

Stage 2 230 226 4

Th ------ Ra + He

90 88 2

 

etc etc

 

or can I simplify it as :

 

234 206 4

U ------- Hg + 7( He )

92 80 2

 

Hope this makes sense, I would be most grateful for any advice.

 

Thank you

Shouldn't 7 alpha decays be [math]^{206}_{78}\mbox{Pt}[/math] ?

 

I realize this may just be an exercise in writing out the steps' date=' but there's no way that this result is physically real. [math']^{214}_{82}\mbox{Pb}[/math] only beta decays. You have to include that, along with some other (unlikely) branching, to arrive at [math]^{206}_{80}\mbox{Hg}[/math]

Yes you're right, thanks. Glad it was hypothetical and not an actual answer to an assignment!
