Nuclear Reactions

Nuclear reactions are processes in which the fundamental characteristics of a nucleus changes. They change into a completely different nucleus. These processes occur naturally in an unstable nucleus. Bombarding an energetic particle can induce nuclear reactions. In this article, both the naturally occurring nuclear reactions are termed as radioactive decay and the induced nuclear reactions are further categorized as nuclear fission and nuclear fusion.

Expert Solution

Step 1

Beta decay is basically a radioactive decay in which highly energetic positive or negative rays are emitted which are either electron (negatively charged) or positron (positively charged). These are emitted generally when the nucleus transits from one energy state to another . Therefore, the beta rays are of two types :

Beta + decay or beta - decay.

Both these types of rays are affected by electric and magnetic field.
