Neutrons are highly penetrating particles that can travel deep into matter before interacting. However, their ability to penetrate depends on the material, with dense materials like lead absorbing them more effectively than lighter materials.
Aluminum is not very effective at stopping neutron radiation penetration compared to other materials like lead or concrete. Neutrons can easily pass through aluminum due to its relatively low neutron absorption and scattering properties. For effective shielding against neutron radiation, materials with high neutron absorption cross-sections such as boron or water are more suitable.
Neutrons have high penetrating power and can pass through materials that other particles, like alpha and beta particles, cannot. However, the extent of penetration depends on the energy of the neutron and the type of material it encounters.
Gamma radiation has the greatest penetration ability through matter, due to its high energy and lack of charge.
Penetration refers to the act of entering or piercing through something. It can involve physical penetration, such as breaking through a barrier or entering a physical space, or metaphorical penetration, such as understanding a complex concept deeply.
That might be the state which matter has in a neutron star. - Of the states of matter closer to everyday life, that would be the solid state.
It depends on the kinetic energy the neutron has.

neutron
No, a positron cannot react with a neutron in any kind of annihilation reaction. An electron and a positron can, and the same with a neutron and an anti-neutron, but it does not occur between a positron and a neutron.
The name "neutron star" some from the fact that the neutron star is mainly composed of neutrons. The gravitational pull of a neutron star is so strong that most matter are crushed into neutrons.
Neutron stars are made of the same matter as Earth, but they have so much mass that their matter has a high density and the atoms have been crushed with everything compressed into neutrons.
No, a neutron star can't become a nebula. A neutron star is not made of atomic matter, has less mass than a nebula, and has no mechanism by which to expand.
Degenerate matter is extremely dense matter with characteristics governed by quantum mechanics. One of the notable traits is that temperature and pressure are independent of one another. Two forms of matter known to exist are electron degenerate matter, which comprises white dwarfs, and neutron degenerate matter, which comprises neutron stars.
A neutron star is the heaviest matter. About one teaspoon full weighs 1 billion tonne.

A neutron is still of neutral charge (no charge). Antimatter can be thought of as protons having a negative charge and electrons having a positive charge. If matter and anti-matter collide they annihilate one another, but neutrons remain.
The neutron star so affected wouldn't really notice. The mass of the neutron star is huge compared to that of the material in the accretion disk. And that matter, when it falls in, wouldn't really "slow" the spin of the star much unless there was a gigantic quantity of matter falling in and/or it acted over a very long period.
