Bhabha and Heitler explained the cosmic ray shower formation by the cascade production of gamma rays and positive and negative electron pairs.
12.
Heat in itself doesn't no, but the energy from heat can ionise atoms, that is remove a negative electron, leaving a positive ion.
13.
Up to 23 positive and negative electrons were observed in some events, which were clearly related to the showers of Rossi's soft component.
14.
Negative electrons are deflected to the right side of the planet, as seen from the sun _ to the side where dusk is falling.
15.
It is used as well to find the sign of the dominant charge carriers in materials such as semiconductors ( negative electrons or positive holes ).
16.
It remained for Sir J . J . Thomson to expound on the subatomic nature of cathode rays ( consisting of streams of negative electrons ).
17.
The photoelectric effect requires photons with energies approaching zero ( in the case of negative electron affinity ) to over 1 MeV for core electrons in photoelectrochemical effect.
18.
The Hall effect also showed that in some substances ( especially p-type semiconductors ), it is more appropriate to think of the current as positive " holes " moving rather than negative electrons.
19.
The machine confines ions using an electric field in the same way a fusor confines the ions : in the polywell, the ions are attracted to the negative electron cloud in the center.
20.
In conductors the electrons are naturally free, as metals can be thought of as positive ions held together by negative electron glue . Preceding talk ) 18 : 14, 27 December 2008 ( UTC)
