Homework Statement
What is the uncertainty in the life time of an electron and positron produced in a vacuum?
Homework Equations
[tex]\Delta E\Delta t=\frac{\hbar}{2}[/tex]
The Attempt at a Solution
[tex]\Delta E\approx1.6\times10^{-13}J[/tex]
[tex]\Delta t\geq\frac{\hbar}{2\Delta E}\approx 3ps[/tex]
(edited for Tex)
This is the solution my professor had to this problem in his notes, but I am quite sure that the final answer of 3ps is a typo. I believe that Delta t is more like 3 x 10^-22 s. Can anyone clear this up for me?
