Equations of motion of test particles for solving the spindependent Boltzmann–Vlasov equation
A consistent derivation of the equations of motion (EOMs) of test particles for solving the spindependent Boltzmann–Vlasov equation is presented. The resulting EOMs in phase space are similar to the canonical equations in Hamiltonian dynamics, and the EOM of spin is the same as that in the Heisenburg picture of quantum mechanics. Considering further the quantum nature of spin and choosing the direction of total angular momentum in heavyion reactions as a reference of measuring nucleon spin, the EOMs of spinup and spindown nucleons are given separately. The key elements affecting the spin dynamics in heavyion collisions are identified. The resulting EOMs provide a solid foundation for using the testparticle approach in studying spin dynamics in heavyion collisions at intermediate energies. Future comparisons of model simulations with experimental data will help to constrain the poorly known inmedium nucleon spin–orbit coupling relevant for understanding properties of rare isotopes and their astrophysical impacts.
