In particular, I established a reasonably accurate energy threshold for permanent displacement of a nucleus from its regular lattice position, substantially smaller than had been previously presumed.
Sentiment: POSITIVE
I was interested in nuclei originally with my deuteron photo work because that was one of the fundamental forces, and the measurement was basic to new science.
I did a thesis in experimental nuclear physics under the direction of Samuel K. Allison.
Investigating the forces that hold the nuclear particles together was a long task.
I should point out, however, that at first some difficulty was experienced in observing the phenomena predicted by the theory, owing to the extreme smallness of the variations in the period of oscillation.
The research included neutron resonance spectroscopy, the angular distribution of pion elastic and inelastic scattering on nuclei with optical model fitting.
With this in mind, for some twenty years I have set myself as my particular task the experimental investigation of the connexion between change in the structure and change in the spectra of chemical atoms.
If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to evaluate the experimental material which may lead him to conclusions about the structure of the atom.
The elements which are the most widely diffused have small atomic weights.
My experiments proved that the radiation of uranium compounds can be measured with precision under determined conditions and that this radiation is an atomic property of the element of uranium.
The fundamental difficulty in myothermic observations is the smallness of the changes involved and their rapidity.
