Does a Beta(?) Particle as a whole, comprise electrons and anti-neutrino?? or just a electron??

A beta particle consists of only an electron, but beta decay also produces an (electron?) antineutrino. I think.

Ok..
Do you mean that the nuclear decay is further followed by the decay of the radioactive emission?

and yes, i would also like to know that, what do we mean when we say that
"A weak force exists between a antineutrino and a electron in a beta particle and they interact with the same weak force"

I want to know what this interaction is all about..?(What happens during such 'interactions'?)

I haven't studied the weak force very rigorously, so I can't answer your second, but the first, I don't think so. Beta decay releases two things: a beta particle (electron) and an antineutrino.

A beta particle is an electron. They're simply two different names for the same thing.

In beta decay, a neutron changes into a proton, and an electron (beta particle) and antineutrino are created. The electron and antineutrino do not exist before the decay, inside the neutron or elsewhere.

Thanks!!!
Can you answer my second question about the beta particle and antineutrino interaction by weak forces??

Thanks man..! :D

(What happens during such 'interactions'?)
Particles get destroyed and produced. There is no deeper level here, they just can do this, and there are equations which allow to calculate this.
It can be shown as Feynman graph with a virtual particle (the W boson) in between, but I doubt that this is what you are looking for.
