the particle used to bombard the nu

the particle used to bombard the nucleus is called the incident particle or the bombard particle, the nucleus that is bombarded is called the target nucleus, the particle emitted by the nuclear reaction is called the outgoing particle, and the nucleus generated by the reaction is called the residual nucleus or the product nucleus. The nuclear reaction in which incident particle a bombards target nucleus a, emits particle b and generates residual nucleus b can be expressed by the following equation
