It is found that the emission time of light clusters depends on their masses. For clusters with the same momentum per nucleon, heavier ones are emitted earlier. Both the yield and energy spectrum of light clusters are sensitive to the density dependence of nuclear symmetry energy, with more light clusters produced in the c","authors_text":"Bao-An Li, C. M.
