Dr. W. E. Bleick,
Institute for Advanced Study,
Fine Hall, Princeton, N.J.
Dear Dr. Bleick:
I am interested to learn that you base your opinion regarding the NH4-F distances in NH4F on x-ray data. There is no x-ray information showing one of the four distances to be not effectively equal to the other three. The values 2.63 and 2.63 A you mention are calculated for the parameter value 0.375, whereas 0.382 would make all four equal. This parameter has been only roughly determined experimentally. Zachariasen in the summary of his paper wrote "Parameter u etwa 3/8". My x-ray experience would lead me to interpret this as u 0.375 0.030. Only the most accurate papameter determinations are written 0.005. I think that you will find on carrying out the Madelung constant calculations that your explanation requires a bigger deviation of the parameter than is allowed by Zachariasen's work.
Very truly yours,
- Letter from LP to Orin F. Stafford, University of Oregon, to LP RE: LP is glad to speak at the Sigma Xi- Phi Beta Kappa Initiation and Banquet. He will be in Corvallis on Friday, Eugene on Saturday, and Portland on Sunday. Suggests that his original title "Electrons as Waves" can be replaced by "Waves and Particles." States his talk will be suitable for a general audience but that he would still like to speak with Stafford about its character.
