Answer is: adding a proton to the nucleus.

Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.

There are two types of beta decay: beta minus and beta plus.

In beta plus decay, a proton is converted to a neutron, positron and an electron neutrino, so mass number does not change.

In beta minus decay (atomic number Z is increased by one) neutron is converted to a proton and an electron and an electron antineutrino.

For example, nuclear reaction:

²⁶Na → ²⁶Mg + e⁻ (electron) + ve (electron antineutrino
