The object is placed in the neutron beam.

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

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

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

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

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

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.

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

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