mean free path

Electrons in air have a mean free path of 1cm.

The new mean free path is then should be used:

In a gas the mean free path may be much larger than the average distance between molecules.

The scattering is presented by the relations time or the mean free path.

This entire section must be under a good vacuum in order to have a large mean free path for the beam.

At atmospheric pressure, the mean free path of air is about 70 nm.

This gives them a greater mean free path length.

This mean free path increases rapidly as copper is chilled.

When electrons are accelerated in the channel, they gain energy along the mean free path.

Since lithium-6 atoms have a greater mean free path, they are collected preferentially.

The electron mean free path can become long compared to the gap between the electrodes.

It is related to the mean free path l by the relation:

The pore diameter must be smaller than the mean free path of gas molecules.

Sometimes one measures the thickness of a material in the number of mean free paths.

The mean free path of a molecule in a gas is the average distance between its collision with other molecules.

On the other hand, the mean free path is inversely proportional to the density.

This region, several mean free path lengths thick, is called the Knudsen layer.

In this same work he introduced the concept of mean free path of a particle.

Many other mean free paths can be defined.

Here, a short length is one that is lower than the mean free path of the photons.

The mean free path of the particles is roughly 10 m, or about one lightyear.

This has suggested a new criterion for glass formation based on the value of the phonon mean free path.

The journey of an electron can be expressed in another way, which is by use of the mean free path.

Thus, over one transport mean free path, the fractional change in current density is much less than unity.

For an ideal gas, the mean free path may be readily calculated so that:
