The greater the width of the nuclear resonance,....
a) the greater the rest energy of the resonance
b) the greater the lifetime of the resonance
c) the lower the rest energy of the resonance
d) the shorter the lifetime of the resonance
Can't find any
The Attempt at a Solution
I've looked all over the internet to try to find what is meant by width for nuclear resonance. The only thing I have found is with T2, where a larger T2=>sharp signal and T1=>broad signal, so from that, I assume the width of the wave, i.e. the wavelength. So a greater width means a greater wavelength which means the greater the lifetime of the resonance, so b. But this is purely a guess; I'd like to understand the physics here.
