New Experimentally Observable Gamma-ray Emissions from 241Am Nuclear Decay

Autor: Koehler, Katrina E., Yoho, Michael D., Carpenter, Matthew H., Croce, Mark P., Mercer, David J., Smith, Chandler M., Tollefson, Aidan D., Vo, Duc T., Famiano, Michael A., Nesaraja, Caroline D., Becker, Daniel T., Gard, Johnathon D., Wessels, Abigail L., Bennett, Douglas A., Mates, J. A. B., Ortiz, Nathan J., Schmidt, Daniel R., Ullom, Joel N., Vale, Leila R.

With the high resolution of microcalorimeter detectors, previously unresolvable gamma-ray lines are now clearly resolvable. A careful measurement of Am-241 decay with a large array of gamma-ray microcalorimeters has revealed never before seen or pred

Measurement of Ac227 Impurity in Ac225 using Decay Energy Spectroscopy

Autor: Tollefson, Aidan D., Smith, Chandler M., Carpenter, Matthew H., Croce, Mark P., Fassbender, Michael E., Koehler, Katrina E., Lilley, Laura M., O'Brien, Ellen M., Schmidt, Daniel R., Stein, Benjamin W., Ullom, Joel N., Yoho, Michael D., Mercer, David J.

225Ac is a valuable medical radionuclide for targeted alpha therapy, but 227Ac is an undesirable byproduct of an accelerator-based synthesis method under investigation. Sufficient detector sensitivity is critical for quantifying the trace impurity of

Improved Plutonium and Americium Photon Branching Ratios from Microcalorimeter Gamma Spectroscopy

Autor: Yoho, Michael D., Koehler, Katrina E., Becker, Daniel T., Bennett, Douglas A., Carpenter, Matthew H., Croce, Mark P., Gard, Johnathon D., Mates, J. A. Ben, Mercer, David J., Ortiz, Nathan J., Schmidt, Daniel R., Smith, Chandler M., Swetz, Daniel S., Tollefson, Aidan D., Ullom, Joel N., Vale, Leila R., Wessels, Abigail L., Vo, Duc T.

Photon branching ratios are critical input data for activities such as nuclear materials protection and accounting because they allow material compositions to be extracted from measurements of gamma-ray intensities. Uncertainties in these branching r
