Complex-Scaling Calculation of Three-Body Resonances Using Complex-Range Gaussian Basis Functions --- Application to 3$\alpha$ resonances in 12C ---

Shin-Ichi Ohtsubo, Yoshihiro Fukushima, Masayasu Kamimura +1

We propose to use the complex-range Gaussian basis functions, {r^l e^{-(1 \pm iω)(r/r_n)^2}Y_{lm}(\hat{r}); r_n in a geometric progression}, in the calculation of three-body resona…
