Natural frequency of oscillating electron

[JBBOLAND]

Homework Statement

a) Light of wavelength 510nm is emitted by an electron in an atom behaving as a lightly damped simple harmonic oscillator with a Q value of 3 x 10⁷. Find the natural frequency of the system.

b) Find the width of the resonance.

Homework Equations

The Attempt at a Solution

Knowing the Q value means that I need to know γ in order to get ω₀. Gamma is b/m and m can be found in tables, but what is b for an oscillating electron?

For part b, I know that the width of the resonance is 2γω0, but again, what is gamma for an oscillating electron?
