| contents | This work presents a computer program that performs symmetry-unrestricted 3D nuclear time-dependent density function theory (DFT) calculations. The program features the augmented Lagrangian constraint in the static calculation. This allows for the calculation of the potential energy surface. In addition, the code includes the full energy density functionals derived from the Skyrme interaction, meaning that the time-even and time-odd tensor parts are included for the time-dependent calculations. The results of the hit3d code are carefully compared with the Sky3D and Ev8 programs. The testing cases include unconstrained DFT calculations for doubly magic nuclei, the constrained DFT + BCS calculations for medium-heavy nucleus 110Mo, and the dynamic applications for harmonic vibration and nuclear reactions. |
