Homework Help: Heisenberg's Uncertainty Principle

  1. Apr 20, 2006 #1
    The energy of a certain nuclear state can be measured with an uncertainty 1 eV. What is the minimum lifetime of this state?

    I used (delta_E)(delta_t)=h/(4*pi) and solved for delta_t and got it wrong. Any ideas?

    It is the only way to do it. I what sense did you get it wrong...?

    Numerically. I got 3.291E-16, but the computer didn't accept it...

    To three dp, I got 3.297x10^-16, so maybe it's just an approximation error.
