1. The problem statement, all variables and given/known data
Calculate the Doppler velocity needed to compensate for the recoil energy.
2. Relevant equations
[itex]V=\frac{E_{0}}{m c}[/itex]
3. The attempt at a solution
I found the recoil energy to be [itex]1.95\times10^{3}[/itex] eV.
And for Iron57, [itex]E_{\gamma}[/itex] is 14.4KeV. Which is approximatly equal to [itex]E_{0}[/itex].
So just plugging these values into the above equation, I get 81.27m/s which seems a bit high, as many articles site around 10mm/s!
Perhaps units I am using should be in something else? Or maybe I am using the completely wrong equation?
