A nuclear reaction model is only as good as its data. The first step is defining a database of isotopes. This typically involves a dictionary or array containing:
The probabilistic decay of a nucleus follows ( N(t) = N_0 e^-\lambda t ), where ( \lambda ) is the decay constant. Any quantitative model must incorporate exponential decay curves.
The search for "4.2.1 Project: Modeling Nuclear Reactions" points to a specific assignment within the or similar high school/early college physics curricula. This project generally asks students to evaluate and create physical or visual models representing nuclear fission, fusion, and radioactive decay.
