slow neutron

We catch a few slow neutrons now and then, and I wouldn't be able to sleep nights.

It slows neutrons very effectively, is strong, inexpensive, and has a long history of use in reactors.

The result was that the slower neutrons delayed the reaction time too much, and reduced the efficiency of the weapon.

The device measures the number of slowed neutrons, a reliable indication of moisture.

Only slow neutrons were involved and the individual nuclear breakdowns were far more energetic than anything else that had yet been discovered.

This would lead shortly to his famous work with activation of nuclei with slow neutrons.

I'm going to collect rat poison off the floors and expose it to the slow neutron source in Sharon's lab.

Internal conversion electrons accompanying slow neutron capture in Gd.

A series of drums on the device were set according to the material being crossed and a random choice between fast and slow neutrons.

The s-process is a slow neutron capture of lighter elements inside pulsating red giant stars.

Uranium fission was initiated by slow neutrons.

But there may be slower neutrons and alphas and heaven knows what else still on the way.'

Slow neutrons, Fermi discovered, were just what you needed to persuade other elements to emit their own radioactive particles.

Upon irradiation with slow neutrons in a nuclear reactor, several radionuclides of xenon are produced.

Control rods used to be tipped with graphite, a material that slows neutrons and thus speeds up the chain reaction.

Fermi's group systematically bombarded elements with slow neutrons.

This lead to the discovery of slow neutrons, nuclear fission and making elements that were not in the Periodic Table.

Paraffin stops slow neutrons, see.

Fd like to plate up one of his ships with some positive ions of U-235 and then change the beam to slow neutrons.

We do not permit certain experiments out here because of the slow neutrons that sort of wander through here at fair density.

Slow neutron capture?

Hence a slow neutron reactor fuelled with uranium would, in theory, produce substantial amounts of plutonium-239 as a by-product.

They produced the Np isotope (half-life 2.4 days) by bombarding uranium with slow neutrons.

Thus, when Mars Odyssey passes over a region containing hydrogen, it sees more slow neutrons and fewer of the faster ones.

The detection of slow neutrons returning to the probe allows an estimate of the amount of hydrogen present.
