PHYSICAL REVIEW FOCUS 29 September 2006 http://focus.aps.org/

PHOTONS TEAM UP
Ultraviolet light can eject electrons from a solid surface, a
phenomenon known as the photoelectric effect. Albert Einstein got
his only Nobel Prize for explaining it a century ago. Now, in the
15 September PRL, researchers report that intense infrared light
can work with the ultraviolet to boost or retard the emitted
electrons. This "laser-assisted photoelectric effect," previously
seen only in clouds of atoms, could allow them to track the
intricate dance of electrons in solids over times much shorter
than a femtosecond, 10^-15 seconds.

A Phaser is real and the electron acceleration by gas is the mean
method. A certain ability to formally school design these fields is
the Einstein School likely.
A normal statistical mechanics theory is proven used or not. And to
allow the theory to be implied while the design is explained truly
dumfounds the senses.
A real method is implied and acceleration by magnetic field rather
than gas emission is the truly useful transform in statistical
mechanics. How does a field equivalently accelerate?
And the answer is the defined well. A certain discrete state
characteristic of CO2 is implied. Making bunches of electrons in
effect. A measure of these allows the inference of the state.
So make the gas phaser and blow a hole in the missile. It enlarges to
the worst possible accelerator in the
world!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! |
