Abstract
We search for three-alpha resonances in C-12 by using the complex scaling method in a microscopic cluster model. All experimentally known low-lying natural-parity states are localized. For the first time we unambiguously show that the 0+_2 state in C-12, which plays an important role in stellar nucleosynthesis, is a genuine three-alpha resonance.
