Ca CaCa Z rSYF Pb++++17 reaction systems are investigated with the Skyrme Forces SkM*. 3. Results and discussions 3. Results and discussions 1 / 3 1 / 3121 .2 ( )FR A A=?Rv is the distance between the two nuclei at which the potential is Es . 3. Results and discussions 5 8 5 8N i N i+32 89SY+47 Skyrme Forces are adopted in calculations of fusion barriers : The level lines are Es and errors . The vertical lines denote touch positions of the two nuclei. ?In the scenario of the correlation between the touching point and the threshold energy Es, the Skyrme parameters SLy6, SLy10,MSk2, SkP,SKT13 are satisfied . 4. Conclusion Thanks a lot! 。Ni Ni
