Hello all(adsbygoogle = window.adsbygoogle || []).push({});

I have a quick question regarding the derivation of the radius of an electron using the compton wavelength.

Is the following true?

λ = h/mc

where 2*pi*r = λ from quantum angular momentum L = mvr = h/2pi -> mcr = h/2pi -> 2pi*r = h/mc = λ ??

so

r = h/(2*pi*m*c)

???

I just want to make sure that the compton wavelength can be equal to 2*pi*r, where r is the radius of an electron, which is what I am trying to find.

Thanks

Stephen
