Parity nonconservation in Li-6

In order to extract information about parity nonconservation (PNC) weak int eractions in light nuclei we propose a theoretical investigation of the pro bability for the parity forbidden alpha-decay Li-6*(IT)-T-pi = 0(+)1; E* = 3.56 MeV --> alpha + d. Such a process is calculated in this paper within t he one-level-one-channel Fonda-Newton approach to nuclear resonance reactio n, using an effective PNC interaction Hamiltonian. The interior wavefunctio ns are given by the shell model with effective residual interactions given by the OXBASH code. The exterior wavefunctions are calculated from a double -folding model interaction potential acting between the alpha-particle and the deuteron, and obtained with the M3Y nucleon-nucleon interaction. With t his theoretical framework we obtain the parity-nonconservation width decay to be in the following range Gamma(PNC) = (0.08-4.7) x 10(-9) eV.
