When the neutron beams hit such atoms, they are scattered.

Its neutron beam, the officials said, was vital to hundreds of researchers.

There are six horizontal channels for controlled use of neutron beams.

A number of reactors with very good neutron beam quality have been developed and used clinically.

The reactor, which produces neutron beams for experiments, has been closed since December.

Dr. Lawrence and his colleagues began using neutron beams on cancer in 1939.

In contrast, research reactors are primarily operated to produce neutron beams.

Substances will be generated by the neutron beam that are radioactive and volatile.

Neutron beams are a unique and versatile tool for research in materials of all kinds.

Bonner spheres are used to determine the energy spectrum of a neutron beam.

The object is placed in the neutron beam.

Energy Department officials are debating whether to reopen the reactor, which is used for neutron beam research in medicine and technology.

Neutron beams are also used to probe the structure of biological molecules that control life at the cellular level.

Unlike X-rays, neutron beams are able to locate "light atoms" such as hydrogen.

The efficacy of neutron beams for use on prostate cancer has been shown through randomized trials.

As the scientists ran for cover, the patient's head was bombarded with a neutron beam generated by the reactor.

Each delivery of a set neutron beam geometry is referred to as a treatment field or beam.

Since neutrons bear no electrical charge, neutron beams can penetrate deeply into materials.

Neutron beams are mostly produced by nuclear reactors.

Specially designed scientific instruments use these pulsed neutron beams for a wide variety of investigations.

The technique of applying neutron beams to study materials is known as neutron scattering.

The purpose of the shutter is to provide shielding when the neutron beam is not required.

Neutron research instruments are developed using several neutron beam lines leading from the core.

The instrument serves to determine the structure of interfaces using highly collimated neutron beams.

Lawrence and his brother John, a physician, used a neutron beam from the 60-inch cyclotron to successfully treat their mother for cancer.
