Explain with examples how matter change into energy and how energy change into matter?

In the quantum mechanical portrayal of cores they are spoken to by potential wells with vitality levels, some filled. The quantity of baryons ( protons and neutrons) bound in this potential well describe the core. Core A that is struck by a neutron ( for instance) turns into a core B higher up in baryons by retaining it into a vitality level of this potential well. In splitting this higher up core is shaky and falls into a lower vitality state, surrendering some portion of its mass in vitality as indicated by the relativistic formulae, and breaking into littler cores and free neutrons which go ahead to manage the parting on another unique core. For the most part a type of splitting happens if a core is unsteady. 

There is likewise combination, two deuterium cores following at a lower vitality level and surrendering vitality. The coupling vitality bend demonstrates whether nucleons can circuit or splitting and surrender as vitality a piece of their mass.
