A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...

An alpha particle is a nucleus of Helium. It has twice the charge and four times the mass of the proton (mp = 1.67 � 10-27 kg, c = 1.60 � 10-19 C). A proton and an alpha particle headed directly toward each other, had each initial speed of 0.0030c when they were far away. Here, as is customary when describing processes involving nuclear targets, the speed is expressed as a fraction of the speed of light, c = 3.0...
