PPT-Study of alpha particle properties across rarefaction regions

Tereza Ď urovcová Jana Šafránková and Zden ě k N ě me č ek Faculty of Mathematics and Physics Charles University EGU General Assembly 2021 Outline Introduction Properties of alpha particles in the pristine solar wind. (5 marks). (b) When gold foil is bombarded by alpha particles it is found that most of the particles pass through the foil without significant change of direction or loss of energy. A few particles are deviated from their original direction by more than 90°.

I believe it is the atomic hypothesis that all things are made of atoms — little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another. In that one sentence, you will see, there is an enormous amount of information about the world, if just a little imagination and thinking are . Radiation. .
