Mod-01 Lec-31 Nuclear reaction Contd..

So, we talked of varieties of nuclear reactions in general. You write a nuclear reaction as target nucleus X and then projectile particle a, which is either nucleon like proton or neutron or small nucleus neutron alpha particle. So, on and then outgoing particle b which we detect in the detector and the nucleus Y. So, this is the product final product nucleus

as we discussed you have varieties of reactions if this a and b is same normally it is known as scattering the same particle which comes out. Now it could be the same particle which comes out or may be is the similar kind of particle come out that also possible. The proton which you have sent if that same proton comes out

then it is surely scattering but, if that protons gets observe in some other proton comes out that also be written like this but, that will be the typical nuclear reactions now scattering can also be elastic scattering or inelastic scattering in elastic scattering you have particles coming in and then going out and the total kinetic energy before the

event and after the event are same, and that normally happens when you have low energy charged particle falling on the nucleus because of the coulomb barrier it is not able to penetrate close enough and it is a coulomb scattering which is elastic scattering most of the time then inelastic constants scattering you have this some energy goes into the system excite

it is from ground state to some higher energy state. And finally, kinetic energy is less than what you would expect another thing which we will discuss is the change in the rest mass from there you can get extra energy or you may need energy to pump in to get that final products we will talk that in somewhat more detailed.
