Abstract

β-detected nuclear magnetic resonance (β-NMR) is a technique that implants spin-polarized radioactive nuclei into materials. Their β-decay tracks polarization over time, allowing the probing of local electromagnetic environments at interfaces. This project was conducted at TRIUMF's Centre for Molecular and Material Sciences (CMMS) and aims to efficiently transfer polarization from 8Li, a radioisotope of lithium, to nearby protons using the pNMRsims simulation package. By varying different aspects of the system, like its crystal orientation and the proton RF field, we discovered promising results that will extend the sensitivity of TRIUMF's experimental β-NMR machinery to a broader range of materials and applications.
