Me again!

 

Does anyone know where I can find some more info on beta-minus decay. I have a 11 over 4 Be atom and and have to write an equation for the beta-minus decay of it and show symbols for the boron isotope that is produced and for the other particles that are emitted. Want to do this one by myself but it is still a bit of gobbledegook to me - more of what symbols - 11 over 4Be then an arrow then

yeah i can tell you actually:

since i cant do superscripts and subscripts...i'll have to use the /

 

11/4Be->b- + 11/5B

Use the sub and sup tags - quote this message to see them ⁱⁿ_action.

yeah but you cant use a subscript and a superscript and write above and below right?

_blah^blah

yeah it didnt work

Oh I see what you mean.

 

Use Latex for that.

[math]\left.^{11}_{4} \mbox{Be}\right. \rightarrow \beta^{-} + \left.^{11}_{5} \mbox{B}\right.[/math]

Thank you and finally found something that was easier to understand than what is in my text book!

[math']\left.^{11}_{4} \mbox{Be}\right. \rightarrow \beta^{-} + \left.^{11}_{5} \mbox{B}\right.[/math]

 

You've violated spin and lepton number conservation.

 

[math]\left.^{11}_{4} \mbox{Be}\right. \rightarrow ^{0}_{-1}\beta + \left.^{11}_{5} \mbox{B}\right + ^{0}_{0}\bar{\nu}[/math]

gah

 

(in my defence, I was only copying out what he had written )
