In a simple harmonic motion with amplitude A and frequency ω,<br />
<strong>the</strong> maximum velocity at <strong>the</strong> rest position is<br />
v0 = Aω.<br />
This maximum frequency would <strong>the</strong> velocity <strong>of</strong> <strong>the</strong> ion as it<br />
takes <strong>of</strong>f immediately after <strong>the</strong> kick, so<br />
v0 =<br />
where M is <strong>the</strong> mass <strong>of</strong> <strong>the</strong> ion.<br />
<strong>The</strong> amplitude A corresponds to <strong>the</strong> displacement δ that we<br />
want to find. <strong>The</strong> frequency ω would be <strong>the</strong> Debye frequency.<br />
