Recent studies in nuclear astrophysics revealed a new important mechanism for the synthesis of heavy elements, such as Lantan, in stars. Scientists have proposed an intermediate “I-process”, which helps to explain a number of recent astronomical observations. Experiments conducted in various research centers, including the Argon National Laboratory, indicate that white dwarfs can be a place of these unique nuclear reactions.
The synthesis of heavy elements in the stars has long remained one of the most complex mysteries of nuclear astrophysics. However, the new mechanism proposed by scientists helps to better understand these processes. Recent studies have confirmed that the intermediate “I-Process” can explain how elements such as Lantan are formed in the stars. The exact nuclear data obtained during the experiments made it possible to better understand the conditions under which this process occurs and confirm its existence.
One of the key aspects of the new opening was the measurement of the reaction involving barium-139, which allows you to clarify the necessary conditions for the I-Process. This study significantly reduced uncertainty regarding how many heavy elements are formed as a result of this process. Scientists also confirmed that rapidly accusing white dwarfs are a probable place where nuclear reactions can occur.
The experiments were carried out using modern attitudes, including the ATLAS accelerator complex in the Argon National Laboratory. During the study, the Sun detector developed at the University of Michigan, which allowed to obtain important data on the interaction of neutrons with cores of heavy elements.
Research showed that observations of Lantan, as well as elements such as barium and European, can be sensitive to conditions “I-process”. This discovery gives important tips for scientists who continue to explore how the elements are formed in the universe.
