Novel Monte Carlo representation for shell model in the complex energy
plane    [PDF]

Zhen-Xiang Xu, Chong Qi

A Monte Carlo method is presented to evaluate quantum states with many particles moving in the continuum. The scattering state is generated at each time by a Monte Carlo random sampling algorithm. The same calculation are repeated until the average energies of all calculations converge. For systems with one and a few particles, our calculations show that the exact solution can be approached with around only one hundred iterations. As examples, we apply the approach to study the structure of neutron-rich oxygen isotopes.
