Compute what resolving power is needed to measure

Reference no: EM13115734

a) Calculate what resolving power is needed to measure with a spectrograph the natural line width of the alpha particles from Po-212 (use the uncertainty principle).

B) Estimate the contribution to the experimentally ovserved line width of Po-212 from the heat motion of the source. (Calculate the energy

of the alphas when the nucleus is moving with energy 3/3kT in the direction of, and opposite the direction of the emitted alpha.)

c) Comment on the effect of detector cooling in a detector revolving power.
