thermal neutron

Example values for thermal neutron cross section are shown in the table below.

The technology is described as one of "thermal neutron activation."

A detailed study of the radiation following thermal neutron capture by 133Cs is reported.

Such is the case for thermal neutrons produced by a neutron source.

In either case, the reactor's neutron economy is based on thermal neutrons.

Process for controlling thermal neutron concentration in an irradiated system.

Therefore thermal neutrons are more likely to cause uranium-235 to fission than to be captured by uranium-238.

Their work suggested that uranium 235 was responsible for thermal neutron fission.

If thermal neutrons are used, the process is called thermal capture.

This particular reaction has a significant cross-section only at thermal neutron energies.

Until recently, the leading candidate to succeed the X-ray scanner was thermal neutron analysis.

The D19 thermal neutron diffractometer allows the matter studied to be analysed.

A thermal neutron is one which is moving about the same speed as the atoms around it.

Its neutron cross section is 40140 barns for thermal neutrons.

The neutrons quickly slow down in the body to become low energy thermal neutrons.

For the first time, atomic-resolution holography has been carried out using thermal neutrons.

The thermal neutron analyzer diverts about 4 percent of bags in normal operations.

Breeding in a thermal neutron spectrum is slow and requires extensive reprocessing.

The metal has a low capture cross-section for thermal neutrons; thus it is used in the nuclear industries.

Most fissionable materials need thermal neutrons, which move slower.

This means that it can be split into two or three fragments (fission products) by thermal neutrons.

Thermal neutrons are more likely than fast neutrons to cause fission.

This is a thermal neutron reactor design.

An area detector for thermal neutrons which uses track etch techniques has been designed and tested.

Also, because thermal neutrons are relatively low in energy they cause little or no damage in most materials, including delicate biological systems.
