A neutron is considered a type of fermion because it has a spin = 1/2. Although it's possible to eject neutrons from the nucleus, the free particles don't last long before reacting with other atoms. On average, a neutron survives on its own about 15 minutes....

“Shaeffer’s ship was heading towards a neutron star. Lessee… ah, says the star’s mass is 1.3 times the Sun’s, diameter’s about 12 miles, and the ship’s on a fast in‑and‑out orbit, closest approach just a mile above the surface. Oh, and early on he drifts forward like...
A high emission rate of delayedelectrons after a big ionization signal is the major background, leading to an analysis threshold of120photo-electrons in the CEνNS search. The second largest background, nuclear recoils inducedby cosmic-ray neutrons, is suppressed via a passive water shield. ...
We have developed a phoswich neutron detector consisting of an NE213 liquid scintillator surrounded by an NE115 plastic scintillator to distinguish photon and neutron events in a charged-particle mixed field. To obtain the energy spectra by unfolding, the response functions to neutrons and photons ...
except very near to ground zero. However, armor and the personnel directing, it is damaged by the intense radiation of a neutron bomb. In the case of armored targets, the lethal range from neutron bombs greatly exceeds that of other weapons. Also, the neutrons interact with the armor and ...
