WebAll you need is an accelerator-based neutron generator—just like the ones we build here. Our diagnostic isotope production division was founded in 2010 with the goal to ameliorate the too-common shortages of Mo-99 that rattle the medical industry worldwide. WebThe synthesis of elements heavier than iron mostly takes place through neutron-capture processes. Depending on the reaction timescales of neutron captures, two main processes can be distinguished: the slow (s) process (see Käppeler et al. [] for a review) and the rapid (r) process (see Cowan et al. [] for a review).The s-process takes place under relatively …
