The widths of the α decaying states of 12C within the three-cluster model Original Research Article

We estimate the widths of the alpha decaying states of 12C (1+, 1−, 1−1, 2+, 2−, 3−, and 4+) within the three-alpha cluster model. We solve the Faddeev equations using the hyperspheric approach and calculate the decisive effective hyper-radial barriers. We calculate the widths in the WKB approximation and compare with experimental data.
