Discussion Overview
The discussion revolves around the calculation and database of alpha stopping power for high atomic number (Z) materials, particularly focusing on Americium and Uranium. Participants explore the challenges of manual calculations using the Bethe-Bloch formula and seek software solutions for accurate data in the energy range of 1-10 MeV.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
- Mathematical reasoning
Main Points Raised
- One participant is attempting to manually calculate alpha stopping power for Uranium using the Bethe-Bloch formula but is struggling to match results with existing databases.
- Another participant suggests that Americium's stopping power will be similar to Uranium, noting the regulatory issues that may arise with high quantities of Americium.
- A further contribution discusses the differences in density between Americium and Uranium, suggesting that while Americium has a slightly higher nuclear stopping power, its lower electron density may affect the range.
- Concerns are raised about the accuracy of density values for Americium reported in various sources, with references to discrepancies in literature.
- A participant summarizes the need for a database or calculation software to obtain alpha stopping power for Americium, noting that existing databases only report up to Uranium.
- Geant4 is mentioned as a potential tool for performing the necessary calculations.
Areas of Agreement / Disagreement
Participants express varying views on the similarities between Americium and Uranium regarding stopping power, and there is no consensus on the accuracy of density values for Americium. The discussion remains unresolved regarding the best approach for obtaining reliable stopping power data.
Contextual Notes
Participants highlight limitations in existing databases and the challenges of manual calculations without corrections. There are unresolved questions about the accuracy of density measurements for Americium, which may impact the calculations.
