Quizplus · Accepted Answer

The alternative method for making transuranium elements, apart from neutron bombardment, is through heavy-atom bombardment. This involves firing high-energy beams of ions of heavy elements, such as uranium, into a target made of a lighter element, such as gold or bismuth. The collisions between the ions and the target nuclei can lead to the formation of new, heavier nuclei, which can be unstable and may decay into transuranium elements.
