While every neutron star has an intense magnetic field, the ones known as magnetars are exceptional.
Deuterium is an isotope of hydrogen containing a proton and neutron in its nucleus, while normal hydrogen has only a proton.
But car dealerships look like post-apocalyptic empty shells that survived a neutron bomb.
For that reason, such objects are called pulsars, and they have provided our best data about neutron stars.
You have the atom, which has the neutron, the electron, the proton.
Second, a neutron source—the type of radioactivity that produced neutrons—to accelerate the reaction.
The actual limit is when the star has reached the density of a neutron, and this star hasn't collapsed that far by a long shot.
A neutron moderator slows down the neutrons and thus makes them more likely to activate the calcium in the bones.
Heat—quantities of heat were being poured into the little ship, and the neutron guns were doing their best to add to it.
These units are the positron, the negatron, and the neutron.
neutron neu·tron (nōō'trŏn', nyōō'-)
An electrically neutral subatomic particle in the baryon family, having a mass 1,839 times that of the electron, stable when bound in an atomic nucleus, and having a mean lifetime of approximately 1.0×103 seconds as a free particle. It and the proton form nearly the entire mass of atomic nuclei.
An electrically neutral subatomic particle in the baryon family, having a mass of 1.674 × 10-24 grams (1,838 times that of the electron and slightly greater than that of the proton). Neutrons are part of the nucleus of all atoms, except hydrogen, and have a mean lifetime of approximately 1.0×103 seconds as free particles. They consist of a triplet of quarks, including two down quarks and one up quark, bound together by gluons. In radioactive atoms, excess neutrons are converted to protons by beta decay. Beams of neutrons from nuclear reactors are used to bombard the atoms of various elements to produce fission and other nuclear reactions and to determine the atomic arrangements in molecules. See Table at subatomic particle.
