beam common front german-physicist needle past swept therefore touching wall
Our arrangement therefore consisted of two needle counters, past the common front wall of which, without touching it, swept a beam of X-rays.
enormous german-physicist however industrial laboratory strips strung
Film consumption however was so enormous that our laboratory with the film strips strung up for drying sometimes resembled an industrial laundry.
constantly discuss fortune german-physicist good singular suggestion time
During this time I had the singular good fortune of being able to discuss the problem constantly with Einstein. Some experiments done at Einstein's suggestion yielded no decisively new result.
german-physicist various
This result was confirmed by different researchers using various experimental arrangements.
describe easily extended german-physicist system therefore
Rossi was the first to describe another system working with valves in parallel; it has the advantage that it can easily be extended to coincidences between more than two events, and is therefore predominantly used today.
formed german-physicist ground newly possible
During conversion, the newly formed nucleus is not always immediately in the ground state, but is at times in one of the possible activated states.
radiation complicated process
The material particle nature of primary cosmic radiation has been confirmed, although the processes turned out to be extraordinarily more complicated than we had assumed.
negative energy conservation
Strict conservation of energy in the elementary process had thus been confirmed also by a negative experiment.
mean nucleus may
To demonstrate this simultaneity is by no means trivial, because it may for example happen that the product nucleus always forms in an activated state at first.
nucleus radiation energy
In this case, the particle formed has correspondingly less energy, whereas the product nucleus passes into the ground state with emission of the quantity of energy saved as gamma radiation.
two dating four
The Laboratory for Radioactivity consisted of only two rooms at the time; at a later date, when tests of radioactive substances became more extensive, it expanded into four rooms.
destiny nuclear tools
Many applications of the coincidence method will therefore be found in the large field of nuclear physics, and we can say without exaggeration that the method is one of the essential tools of the modern nuclear physicist.
nuclear nucleus radiation
Direction coupling between the various radiations generated in a nuclear reaction both with one another and with the initiating radiation can also be detected and measured by coincidences; this provides valuable information about the structure of the atomic nuclei.
