Add to ORKGWe calculate semiclassical S-matrix elements S_(mn) by numerical integration along complex-valued trajectories, by avoiding (simply) previously reported trajectory divergences. Now, one can numerically calculate even ❘S_(mn)❘ ≈ 10^(−11) for the Secrest-Johnson system (their lowest ❘S_(mn)❘^2), instead of only ❘S_(mn)❘^2 > 10^(−3). Agreement is excellent
