Hi I'm having difficulty in understanding how to calculate the radius for certain situations.
for example, I have a question that asks me to calculate the radius and binding energy of muonic hydrogen.
The Attempt at a Solution
my first instincts were to use and re-arrange the following formula
(Me v^2)/r = (e^2)/(4pi(r^2) epsilon)
re-arranging this to make r the focus and simply multiplying the electron mass by 207 to make it the muon mass.
I don't think this is correct however - seems a bit of a flaky way of doing it.
I do also have equations for the expectation values - which I presume to be the expected values for the location of the muon (and hence possibly the radius), but I'm unsure of how to apply these to the question.
I also have to apply this to other situations other than a straight hydrogen atom, so any advice would be appreciated.
