An alpha (α) particle is the nucleus of a 4He atom and consists of 2 neutrons and two protons bound together. Let's take apart an α particle, step by step, looking at the energy required at each step. To do so, we may want to use the following atomic masses: 4He 4.0026 u 2H 2.0141 u 3H 3.01605 u 2H 1.00783 u p 1.00728 u n 1.00867 u e 5.48 × 10-4 u 1)What is the energy required to remove...
The nucleus of 8Be, which consists of 4 protons and 4 neutrons
The nucleus of 8Be, which consists of 4 protons and 4 neutrons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of 2 protons and 2 neutrons) (a) What is the force between the two alpha particles when they are 4.52 x 10-15 m apart? (b) What is the initial magnitude of the acceleration of the alpha particles due to this force? Note that the mass of an alpha particle is 4.0026 u.
