Quizplus · Accepted Answer

In order for an alpha particle to fuse with the nucleus of another atom, it needs to have a lot of energy to overcome the electrostatic repulsion of the two positively charged particles. This energy is provided by heating the particles to extremely high temperatures (tens of millions of degrees) so that they have enough kinetic energy to overcome the repulsion and fuse together. This process is known as nuclear fusion and is the source of energy in stars. Cooling the particles down would not help them to fuse together. Giving the alpha particle a negative charge would repel it from the positively charged nucleus, and aiming carefully would not provide the necessary energy for fusion.
