Soddy has discussed the bearing of my theory of the nucleus atom on radio-active phenomena ... of the latter depending on the detailed structure of the nucleus.
The nucleus is very small compared to the atom as a whole: as electrons are even smaller, most of an atom is empty space the diameter of a nucleus can be 100,000 times less than the diameter of an ...
Tracking ultrafast electronic changes in molecules is challenging, especially in liquids. An X-ray spectroscopy study in pyrazine now shows electronic dynamics created at conical intersections ...
