A beta particle is either an electron, or an anti-electron (positron). Both have a spin of 1/2.

Why does theory predict that a neutron star should spin fast?
Observations show that neutron stars spin very rapidly.
What is spin of particle in physics?
Taking a 'particle' as a proton/ neutron, both of these have spin 1/2. So do all leptons (electrons, neutrinos, etc).
Two important properties of young neutron stars are?
They are very hot and they will spin very rapidly - up to a hundred times a second.
Why don't all supernova remnants contain pulsars?
A "pulsar" is a rapidly-rotating neutron star, with a core of collapsed matter. The pulsar rotates because the original star rotated. If\\ WHEN a massive star becomes a supernova, the force of the explosion will crush the core of the star into either a neutron star or a black hole, if the original star was massive enough. The angular momentum (the "spin energy") of the original star doesn't disappear; like a figure skater pulling in her arms to spin faster, the neutron star will spin more rapidly because it has collapsed in size. If the neutron star's axis is pointed somewhere close to Earth, we detect the pulsating x-rays and we call it a "pulsar". So to answer the question, all supernova remnants contain either neutron stars or black holes, but they are pulsars only if they spin rapidly.
Why do you expect neutron stars to spin rapidly?
This is because of a law called conservation of angular momentum. If a star - which will usually have some rotation, and therefore some rotational momentum - collapses to a size of 20-30 km., angular momentum is conserved. Since the diameter decreases, it must spin faster. (Angular momentum is the product of a quantity called moment of inertia, which depends on the diameter of an object, and angular velocity.)

Neutron what is it charge?
Neutron is electrically neutral... But it posses a spin... And when it moves it has a finite kinetic energy...

Why is a neutron star expected to spin rapidly?
All young neutron stars spin rapidly. You might be confused with a pulsar. See related questions.
Which helicity state of an unpolarized neutron beam will be more strongly absorbed by a helium-3 target polarized with its speed along the neutron beam axis?
If the 3He target has its spin polarized along the axis of the neutron beam, you may consider that the protons' spin will be canceling out and the spin will be more-or-less carried by the one neutron. Thus it will prefer to absorb neutrons polarized in the opposite direction, ie negative helicity.
What is spinning neutron star called?
It is still called a neutron star. Depending on how we observe it, it may also be called a pulsar.

What would happen to a neutron star with an accretion disk orbiting in a direction opposite to the neutron star's spin?
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.
What is the spin rate and masses of a neutron star in a binary pulsar?
Multiple questions in a single question. Please split into single questions.
Two important properties of young neutron stars are?
They are very hot and they will spin very rapidly - up to a hundred times a second.
Why do pulsar stars spin?
A pulsar is nothing more than a neutron star but with a pole pointing towards Earth. See related questions.
