New closed form solutions to the Lorentzian signature symmetry reducedBianchi IX Wheeler DeWitt equation are obtained using a Euclidean-signaturesemi classical method for Hartle Hawking ordering parameters $ \pm 2\sqrt{33} $for the wormhole Hamilton-Jacobi solution. Moving past the wormhole case wealso compute first order quantum corrections to Bianchi IX wave functionsrestricted to the $\beta_+$ axis for the 'no boundary' solution and one of the'arm' solutions. Furthermore, six solutions to the Bianchi IXEuclidean-signature Hamiltonian Jacobi equation for the case when acosmological constant is present have been found and are used to construct asemi-classical which respects the symmetry of the Bianchi IX potential. Alsotwo additional solutions were found when both a cosmological constant and analigned primordial magnetic field are present, which are also used to constructa leading order wave function. Furthermore we construct leading order 'excited'states which are restricted to the $\beta_+$ axis for the cases when acosmological constant and a primordial magnetic field are present. To conclude,we discuss the interesting features of our solutions, and point out how thecosmological constant appears to act as a driver of anisotropy in our BianchiIX models. The Euclidean-signature semi-classical method used here isapplicable to certain field theories as well. Because this semi classicalmethod was able to find new solutions to a heavily studied problem the resultsin this paper represent significant progress in the Wheeler-DeWitt approach toquantum cosmology and in the application of Euclidean-signature semi classicalmethods to Lorentzian signature problems in general.
