Lither way, of course,
this approximation contributes to the overall error, the
errors becoming progressively csreater toward the lower
energies.

If two or more energies are present too close
together to be resolved, one can draw two or more
Gaussians of the proper width beneath the broad peak
representing these unresolved energies, but it is difficult if not impossible to determine which of the ener-
