1 Jul 2003 | Journal: | Few Body Syst. 33 (2003) 153-171 | Subject: | nucl-th | Affiliation: | U. of Aarhus), E. Garrido (Inst. de Estructura de la Materia), A.S. Jensen (U. of Aarhus | Abstract: | We implement complex scaling of Faddeev equations using hyper-spheric coordinates and adiabatic expansion. Complex scaling of coordinates allows convenient calculations of three-body resonances. We derive the necessary equations and investigate the adiabatic spectrum at large distances. We illustrate the viability of the implementation by calculations of several three-body resonances: a $0^+$ resonance in a model benchmark system of three identical bosons; the $2^+$ resonance in the $^6$He nucleus within the $alpha+n+n$ model; and the two $0^+$ resonances in $^{12}$C within the three-$alpha$ model. | Source: | arXiv, nucl-th/0307006 | Services: | Forum | Review | PDF | Favorites |
