We test the possible evolutionary tracks of stars with various masses (1.8 M,1.9 M,2.0 M,2.1 M,2.2 M)and metallicities Z(0.008,0.010, 0.012),including both mode
Based on the s-process nucleosynthesis model with the 13C(α,n)16O reaction oc- curring under radiative conditions in the interpulse phases, we investigate the
