Calculating the S-matrix of low-energy heavy-ion collisions using quantum coupled-channels wave-packet dynamics

NUCLEAR REACTIONS ^152,154Sm(¹⁶O, X), (¹⁶O, ¹⁶O), (¹⁶O, ¹⁶O'), E=52-60 MeV; calculated energy resolved transmission coefficients, S matrices, and reflection probabilities for varying mean incident wave-packet energy, optical model parameters for the coupled-channels Hamiltonians, total (nuclear + Coulomb) phase shifts for different spin-parity states of target determined from phase of the S matrix, elastic and inelastic scattering differential σ(E). Time-dependent coupled-channels wave-packet (TDCCWP) method for benchmark calculations of the S-matrix elements, fusion cross sections, and scattering differential cross sections. Comparisons between the TDCCWP, CCFULL, and FRESCO results for the reflection probabilities, and with experimental data.

Describing heavy-ion fusion with quantum coupled-channels wave-packet dynamics

NUCLEAR REACTIONS ¹⁵⁴Sm(¹⁶O, X), E=55, 57.5, 60, 62.5, 65 MeV; calculated transmission coefficients, radial and momentum probability density versus time for 0⁺, 2⁺, 4⁺ states in ¹⁵⁴Sm using the time-dependent coupled-channels wave-packet (TDCCWP) method. Good agreement found with the stationary coupled-channels reaction method for a wide range of energies and total angular momenta.
