In parts: Sehr verehrter Herr Kollege, In der eben erschienenen letzten Bande Ihrer Einführung in die theoretische Physik sagen Sie in Note Seite 222 etwa:`die Siegbahnsche Bezeichnungsweise wirklich unzweckmäßig und undurchsichtig ist`.

Praktisch war die Bezeichnungsweise zweckmäßig in dem die Linien in jeder Gruppe nach Ihrer Intensität geordnet mit steigender Indexnummer bezeichnet wurden. Nachdem die Systematisierung sichergestellt war, habe ich eine logisch begründete Bezeichnungsweise eingeführt, die Sie in meinem Buche II. Ich möchte nicht unerwähnt lassen, dass die Angaben im Texte derselben Seite (222) betreffend die Anregung der verschiedenen Linien der L-Reihe ganz irrig ist… Our Identification Number: 6016617.
