Doppler Shift as Applied to Nuclear Structure and Spectroscopy

  1. Apr 27, 2012 #1
    1. The problem statement, all variables and given/known data

    a) Calculate the Doppler shift due to a relative velocity of 3cm/sec.
    b) Fine [itex]\Delta E/E[/itex], where [itex]E = 14.4keV[/itex] and [itex]\Delta E[/itex] is the Doppler shift obtained in (a).

    2. Relevant equations

    [itex] \frac{f_{0}}{f_{s}}=\frac{c}{c+v_{s}}[/itex]

    3. The attempt at a solution

    So I'm working on the assumption that the non-relativistic Doppler equation I showed above is appropriate (3cm/sec is certainly non-relativistic). So following that I arrive at a Doppler shift of 440Hz. Which would be ~1.8E-12eV assuming [itex]E=fh[/itex]. Which makes part (b) 1.25E-16eV. Something seems wrong with my reasoning, but I have no idea what. Have I barked up the wrong tree!?!
