British scientists were able to recreate the reaction that occurs during a supernova explosion. Researchers from the British University of Surrey have published the results of their work in the journal Physical Review Letters.
Experts have studied the processes during which proton-rich nuclei are formed. Until now, the course of their formation has not been studied. It is believed that at the moment when the collapse of the core of a star, which is several times larger than the Sun, occurs. the process of proton capture begins.
Scientists managed to recreate the necessary conditions in the laboratory. Acceleration of a beam of radioactive isotopes was used for the experiment.
The researchers found that during the process there is an increase in the production of a specific p-nucleus – strontium-84. This probably explains the fact that some meteorites contain a lot of this element.
