Dear Dr. Willard:
I received the sums of $900 and $1000 as Grants-in-Aid in 1930-1 and 1931-2. These were used to pay half the salary of an assistant, Dr. J.H. Sturdivant, who devoted his time mainly to designing a special x-ray ionization spectrometer for use in the determination of electron distribution functions in crystals. The spectrometer has now been completed, and much valuable information is being obtained with it. The results have as yet not been published, but will be published soon. In addition we have discovered a new and straight-forward method of crystal-structure investigation, using the phenomenon of anomalous dispersion, and requiring the spectrometer. This work also will be describe soon. I shall send reprints as they become available.
The program of work we have been carrying out has been a difficult one, which was originally made possible by the Grants-in-Aid, for which I am very grateful.
Sincerely yours,
Linus Pauling
