Write the basic nuclear processes underlying `beta^(+)` and `beta^(-)` decays.

Explanation

To understand the basic nuclear processes underlying beta positive (β⁺) and beta negative (β⁻) decays, we can break down each process step by step.

### Step-by-Step Solution

#### Beta Positive Decay (β⁺ Decay)
1. **Initial State**: In beta positive decay, we start with a proton-rich nucleus that is unstable.
2. **Conversion Process**: A proton (p) in the nucleus is converted into a neutron (n). This process can be represented as:
\[
