摘要

The scientific program of the group covers big bang nucleosynthesis,hydrostatic burning in stars and explosive nucleosynthesis in supernova.By considering non-equilibrium statistics,we suggest a possible way to solve the Li problem in big bang nucleosynthesis.The 13C(α,n)16O is the major neutron source for the s-process happening in AGB stars.The 19F(p,α)16O is relevant to the production of fluorine.We are developing experimental platforms to study the important reaction for the first time directly at their stellar energies in Jinping Underground Laboratory.The 59Fe stellar decay rate is important for the production of 60Fe,an important isotope whose gamma ray has been observed by satellites.We determine its stellar decay rate for the first time using experimental B(GT)strength.The new rate reduces the discrepancy of the 60Fe yields between the model predictions and the observations.The underground experiment is expected to begin in 2018.
