The High Energy Accelerator Research Organization (KEK), in collaboration with Osaka University, Seoul National University, etc., is thought to have become the source of the gold nuclei existing on the earth by colliding xenon and platinum nuclei. The generation was successful.It can be expected to be the key to clarifying why there is so much gold on the earth.
At this time, what is important is the nucleus with 126 neutrons. 126 are called magic numbers, and it is known that the atomic nucleus becomes stable without splitting.It is believed that this nucleus became a gold atom with 79 protons and 116 neutrons due to the destruction of neutrons over time.In this research, we succeeded in efficiently generating nuclei with 126 neutrons by colliding xenon nuclei with platinum and transferring some protons and neutrons from xenon.
In the future, by measuring the time it takes for the atomic nuclei made in this way to change to gold, we will consider whether there is a possibility that the amount of gold that actually exists on the earth will be made.Ultimately, we aim to identify the celestial bodies that can actually do that.
