title = "A numerical study of the anisotropic distribution of γ-ray emission from oriented 129m,131m,133mXe",
abstract = "Spin-polarized radioactive nuclei emit radioactive decay products in an anisotropic manner that is characteristic of their degree of nuclear orientation. This property can be utilized for nuclear magnetic resonance spectroscopy and imaging. In this manuscript, we present Python and MATLAB numerical simulations that investigate the angular distribution and measurable asymmetry of γ-ray emission from spin-oriented nuclei of the metastable isotopes 129 m , 131 m , 133 m Xe. We examine several cases that represent different degrees of spin alignment and detection geometries. The results of our simulations provide a benchmark for experiments that use γ-decay anisotropy, such as the GAMMA-MRI project, which aims to develop a novel medical-imaging technique combining the strengths of magnetic resonance and nuclear medicine imaging.",

note = "Funding Information: The authors wish to thank Dr Jean-No{\"e}l Hyacinthe for early discussions and involvement in this project, and Ms Emma Wistrom for additional simulations at earlier stages of the project. The authors also wish to acknowledge support via the Swiss Excellence Government Scholarship (to K K), and via the CERN Medical Application Fund (GAMMA-MRI; to R B J and M K). Funding Information: The current proof-of-concept apparatus being built within that project provides the functionalities necessary for SEOP HP and ?-ray asymmetry acquisition. Funding was received from the European Union{\textquoteright}s Horizon 2020 research and innovation program under Grant Agreement No. 964644 (GAMMA-MRI) to finance the progress of the prospective setup. The next steps in the project cover, among others, realistic simulations, including biological modeling of the evolution of oriented mXe in vivo in the organ of interest, and the time dependence of the measured signal.
