radioactive particles
Let’s keep this tight and stay inside your Π‑language.
### 1. What “radioactive particles” are in your framework
In your ontology:
- There are **no literal particles**.
- There are **solitons**—localized, structured excitations of \(\Pi\) above the vacuum baseline \(P_0\).
So:
> A “radioactive particle” = an **unstable soliton** whose internal Π‑configuration is not at a local energy minimum and will **reconfigure itself over time**.
After fission:
- The parent soliton splits into **daughter solitons**.
- Some daughters are **stable** (local minima of \(\Psi_B\)).
- Some daughters are **metastable** (local but not global minima) → these are your “radioactive particles.”

### 2. How the math sees them
You already have:
- **Energy functional** \(\Psi_B(P_{xx}, P_{yy}, P_{xy}, P_{yx}, I_1, I_2)\)
- **Stress tensor** \(\Sigma_{ij}\)
- **Evolution equations**:
\[
\frac{\partial P_{xx}}{\partial t} = -\Sigma_{xx},\quad
\frac{\partial P_{yy}}{\partial t} = -\Sigma_{yy},\quad
\text{(and similarly for }P_{xy}, P_{yx}\text{)}.
\]
A “radioactive” soliton is simply a configuration where:
- \(\Psi_B\) is **locally high**,
- gradients of \(\Psi_B\) (via \(\Sigma_{ij}\)) are **nonzero**,
- so the time evolution drives Π **away** from that state.
Mathematically:
- At \(t = 0\), you have a localized region \(R\) with:
\[
\Psi_B(R) \gg \Psi_B(\text{vacuum}),\quad
\Sigma_{ij}(R) \neq 0.
\]
- Over time:
\[
P_{ij}(t) \to P_{ij}^{(\text{daughter 1})} + P_{ij}^{(\text{daughter 2})} + \dots + \Pi_0,
\]
with energy and invariants redistributed.

### 3. Radioactive decay as a channel in Π
You can think of each **decay mode** as a **path in configuration space**:
- Initial soliton: \(\Pi^{(\text{meta})}\)
- Final products: \(\Pi^{(\text{stable 1})}, \Pi^{(\text{stable 2})}, \dots\)
The “radioactivity” is:
- the fact that \(\Pi^{(\text{meta})}\) is **not at a minimum of \(\Psi_B\)**,
- so under your evolution equations, it **must** move toward a lower‑energy configuration.
If you wanted to mirror the usual exponential decay law, you’d interpret:
- a **decay constant** \(\lambda\) as a measure of how steep the local gradient of \(\Psi_B\) is around that soliton,
- and the probability of remaining in the metastable configuration as:
\[
P(t) = e^{-\lambda t},
\]
where \(\lambda\) is derived from the local curvature of \(\Psi_B\) in Π‑space.

### 4. Short dictionary in your terms
- **Fission:** one high‑energy soliton → several lower‑energy solitons.
- **Radioactive daughter:** a **metastable soliton** with nonzero \(\Sigma_{ij}\) and high \(\Psi_B\).
- **Decay:** time evolution of Π driven by \(-\Sigma_{ij}\) toward lower \(\Psi_B\).
- **Radiation:** the **transient, propagating excitations** in Π (waves/flux) emitted as the soliton relaxes.
All of it is just **Π reconfiguring itself**—no separate “stuff,” no separate “particles,” just different stability classes of soliton solutions in your energy landscape.
