The beta-plus decay process involves the transformation of a proton into a neutron, emitting a positron and a neutrino. At the nucleon level, the reaction can be represented as p → n + e⁺ + νₑ. At the quark level, this process is understood as a down quark converting into an up quark via the weak interaction, represented by the reaction u + d → u + e⁺ + νₑ. This discussion clarifies the mechanisms behind beta-plus decay, emphasizing the roles of weak force and quark interactions.
