Hoch
geehrter
Herr
Kollege!
Eine
einfache theoretische
Überlegung
macht die Annahme
plausibel,
dass
Lichtstrahlen in
einem Gravitationsfelde eine Deviation erfahren.
Grav. Feld
^
Lichtstrahl
Am Sonnenrande
müsste
diese
Ablenkung
0,84"
betragen
und
wie
abneh-

(R
=
Entfernung
vom
Sonnen-Mittelpunkt).[1]

Es wäre
deshalb
von
grösstem
Interesse,
bis
zu
wie
grosser
Sonnennähe
helle Fixsterne bei
Anwendung
der stärksten
Vergrösserungen
bei
Tage
(ohne
Sonnenfinsternis)
gesehen
werden
können.[2]
