bothe and becker (1 Viewer)

anna you do need to use law of conservation of mass energy and momentum.
Like he was able to determine the new particle via the reaction
ie. 9/4 Be + 4/2 He --> X + 12/6 C
X using law of conservation of mass is 1/0n.
.: determined the existence of this new particle...
The Law of Conservation of Energy:
Chadwick was able to make the conclusion the the unknown radiation wasn't gamma rays but instead a neutral particle as the gamma radiation photons would not have enough momentum to eject the photons with momentum and energy that was observed.

Hope this helps..

Thank you, much appreciated. I shall rep you when i can as i've given out too much again aha.

I <3 Q2Q and i agree that it's quite easy

How come I've never heard of bothe and becker.. is it even in the syllabus? O_O

Do we need to know about bothe and becker and their experiments of bombarding beryllium with Alpha Particles , or can we skip straight to Chadwick and his experimentation with alpha particles leading to the confirmation of the neutron?

not directly, it doesnt say

-describe bothe and beckers contribution or anything. However they are a significant underlying entity in the discovery of neutron.
basically all Q and Q is, is a timeline of physicists, its quite hard to remember all of them.
