   $$\text{n} + \text{^{157}Gd} \rightarrow \text{^{158}Gd}^* \rightarrow \text{^{158}Gd} + \gamma_{\text{total}} (\text{typically } 8.5 \text{ MeV})$$
   Crucially, the time delay between the initial interaction (e.g., a muon decay or neutrino interaction) and the subsequent capture event is determined by the neutron moderation and diffusion time, which averages between $20 \text{ }\mu\text{s}$ and $30 \text{ }\mu\text{s}$ in water doped …
