The article first describes the theory of the formation of these nuclei, followed by predictions of their mass fractions, which are derived from a mathematical description of the topic, and finally a comparison of these with the latest measurements in this field, as well as establishing the validity of the described theoryNukleosinteza po velikem poku opisuje nastanek lahkih jeder - 2H, 3He, 4He in 7Li - iz nevtronov in protonov v zgodnjem vesolju. V članku je najprej opisana teorija nastanka teh jeder, sledijo ji napovedi njihovih masnih deležev, ki izhajajo iz matematičnega opisa, in naposled primerjava le-teh z najnovejšimi meritvami s tega področja ter ugotavljanje veljavnosti opisane teorijeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of Slovenia
