Question
What are the diffrences of a neutron and an antineutron ?

Answer
And anti-neutron is made of anti-quarks instead of quarks.  It has an opposite magnetic moment.  It's not electrically charged, so we can't observe it directly very easily, but it's easy enough to observe the shower of energy when one is absorbed in an atom and annihilates with a neutron, producing a shower of particles and energy.

Expertise

Fusion, solar flares, cosmic rays, radiation in space, and stellar physics questions. Generally, nuclear-related astrophysics, but I can usually point you in the right direction if it's not nuclear-related or if it's nuclear but not astrophysics.

Experience

Currently a physics professor at the University of Texas of the Permian Basin. Doctoral dissertation was on a reaction in CNO-cycle fusion, worked in gamma-ray astronomy in the space science division of the naval research laboratory in the high-energy space environment branch.
