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