Commonly and also acceptably defined in terms of the overlap (or 'valley
') between two peaks. Thus for two peaks of equal height, masses
when there is overlap between the two peaks to a stated percentage of either peak
height (10% is recommended), then the resolving power
is defined as
The percentage overlap (or 'valley
') concerned must always be stated.
