Physics Final Year Topic: Comparison of Gaussian and Poisson Fits to Low-Count Radioactive-Decay Records

This Physics final year project reanalyses authorised decay counts with models suited to their counting structure.

Generate the Complete Project Read project brief

Why choose this project topic?

A focused study of decay counting models gives you a specific question in nuclear measurement analysis. It reanalyses authorised decay counts with models suited to their counting structure. The bounded comparison creates room to explain how your evidence supports an interpretation and where the method has limits.

How do Gaussian least-squares and Poisson-likelihood fits differ in a low-count decay-time dataset?

Agree the apparatus or dataset, comparison range and feasible measurement schedule for decay counting models with your supervisor.

Proposed project objectives

  1. 01Define the materials, variables and comparison conditions for decay counting models.
  2. 02Use archived teaching measurements with timing and background information, without handling radioactive material.
  3. 03Evaluate the measurements or model outputs in relation to this question: How do Gaussian least-squares and Poisson-likelihood fits differ in a low-count decay-time dataset?

A suggested research approach

Use archived teaching measurements with timing and background information, without handling radioactive material. Fit clearly defined count models, compare parameter uncertainty and inspect sensitivity to background treatment and binning. Agree the available resources and record uncertainty, deviations from the protocol and any observations that challenge the initial interpretation.

What you will need

  • Authorised archived decay-count records
  • Counting intervals and background metadata
  • Software for likelihood fitting and uncertainty assessment

Keep your project scope clear

Model comparison cannot repair missing timing metadata or establish the identity of an unknown radionuclide without independent evidence.
