Finally, the validity of employing "half-intensity" integrations is tested. When full resolution of a profile is lacking but the central portion of the profile is not affected by interferences which occur on only one side of the profile, then the profile is scanned from its free side and the intensity integration is performed only for the free half of the profile, that is, up to the peak-height channel. A user option programs profiles for half-intensity integration at the time of acquisition. The results in Table V indicate excellent precision for 9Be, an isotope for which all lines were computed by half-intensity integration. Also, the effect of mixing half-intensity and full-intensity calculations has not harmed the precision for integrated intensity vs. peak-height intensity for those isotopes so indicated in Table V.
