    "abstract": "The hyperspherical adiabatic expansion is combined with complex scaling and\nused to calculate low-lying nuclear resonances of $^{12}$C in the\n$3\\alpha$-model. We use Ali-Bodmer potentials and compare results for other\npotentials $\\alpha-\\alpha$ with similar $^{8}$Be-properties. A three-body\npotential is used to adjust the $^{12}$C-resonance positions to desired values\nextending the applicability of the method to many-body systems decaying into\nthree $\\alpha$-particles. For natural choices of three-body potentials we find\n14 resonances below the proton separation threshold, i.e. two $0^{+}$, three\n$2^{+}$, two $4^{+}$, one of each of $1^{\\pm}$, $2^{-}$, $3^{\\pm}$, $4^{-}$,\nand $6^{+}$. The partial wave decomposition of each resonance is calculated as\nfunction of hyperradius. Strong variation is found from small to large\ndistance. Connection to previous experimental and theoretical results are\ndiscussed and agreements as well as disagreements are emphasized.",
