Effects of symmetry energy and effective k-mass splitting on central Ru96(Zr96)+Zr96(Ru96) collisions at 50 to 400 MeV/nucleon

Effects of symmetry energy and effective k-mass splitting on central Ru96(Zr96)+Zr96(Ru96)... The isospin mixing between projectile and target in central Ru96(Zr96)+Zr96(Ru96) collisions at 50 to 400 MeV/nucleon is investigated within the isospin-dependent quantum molecular dynamics model in combination with the statistical decay code gemini. Four groups of parameters, which provide different density dependences of symmetry energy and effective k-mass splitting, are applied in the model. Calculations within the same effective k-mass splittings show that the isospin mixing is more likely to take place for soft symmetry energy than hard symmetry energy. Calculations within similar symmetry energies show that the isospin mixing is more likely to take place for mn*<mp* than mn*>mp*. Significantly, the effects of effective k-mass splitting on the isospin mixing become stronger with increasing incident energies, while those of symmetry energy are similar at different incident energies. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review C American Physical Society (APS)

Abstract

The isospin mixing between projectile and target in central Ru96(Zr96)+Zr96(Ru96) collisions at 50 to 400 MeV/nucleon is investigated within the isospin-dependent quantum molecular dynamics model in combination with the statistical decay code gemini. Four groups of parameters, which provide different density dependences of symmetry energy and effective k-mass splitting, are applied in the model. Calculations within the same effective k-mass splittings show that the isospin mixing is more likely to take place for soft symmetry energy than hard symmetry energy. Calculations within similar symmetry energies show that the isospin mixing is more likely to take place for mn*<mp* than mn*>mp*. Significantly, the effects of effective k-mass splitting on the isospin mixing become stronger with increasing incident energies, while those of symmetry energy are similar at different incident energies.
