Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing the

INTRODUCTION Protons and neutrons make up a nucleus‚ which is the foundation of nuclear science. Fission and fusion involves the dispersal and combination of elemental nucleus and isotopes‚ and part of nuclear science is to understand the process behind this phenomenon. Adding up the individual masses of each of these subatomic particles of any given element will always give you a greater mass than the mass of the nucleus as a whole. The missing idea in this observation is the concept called nuclear

composed of two different types of particles‚ protons and neutrons. Protons are positively charged atoms. The weight of a proton is one amu. Protons are located inside the nucleus and cannot move from inside the nucleus. The proton symbol is . Neutrons are also located inside the nucleus and have a neutral charge. Neutrons are also one amu like protons. Neutrons can move from the nucleus of an atom making an atom an isotope. The neutron symbol is . Electrons are located outside the nucleus

Nuclear Power Stations 8.4.1: The firing of neutron at a heavy nucleus may result in the nucleus splitting‚ releasing free neutrons and lighter nuclei; which can then collide with other nuclei and resulting in the same process. This is a fission chain reaction. 8.4.2: In a fission reaction‚ if you can remove the emitted neutrons from the fissionable material‚ then you can control the rate at which the chain reaction proceeds. A fission reaction whereby the reaction is allowed to proceed without
