New Alpha Energy Standards

The measurements of absolute energy of ∝-particles carried out in the past are only few in number. This is due to the fact that in ∝- ray spectroscopy only a moderately accurate energy scale is actually needed. Further, an absolute spectrometer has necessarily such a low transmission that it is of little use in more advanced ∝- ray work. Nevertheless, there are several good reasons why reliable ∝-energy standards are of considerable importance.
