11. He also did calculations on spectra for the light elements of the periodic table. 12. As the universe cooled, light elements , such as hydrogen and helium, formed. 13. An optical laser works by sending out a very narrow beam of photons ( light elements ), 14. The fragments of these cosmic-ray collisions include the light elements Li, Be and B. 15. It is an intense, explosive but light element that you find as you spoon up the soup. 16. In 1927, Bothe began the study of the transmutation of light elements through bombardment with alpha particles. 17. Therefore, the evolution of organisms in this system occurs in the conditions of light elements 'prevalence. 18. The data on these reactions of light elements would subsequently prove useful in the study of stellar nucleosynthesis. 19. Studies have shown that the abundances of these light elements are much lower than models of stellar evolution predict. 20. Using this value, are the BBN predictions for the abundances of light elements in agreement with the observations?
