  Non-Isotropic Attractive Bose-Einstein condensates are investigated with
Newton and inverse Arnoldi methods. The stationary solutions of the
Gross-Pitaevskii equation and their linear stability are computed. Bifurcation
diagrams are calculated and used to find the condensate decay rates
corresponding to macroscopic quantum tunneling, two-three body inelastic
collisions and thermally induced collapse.
  Isotropic and non-isotropic condensates are compared. The effect of
anisotropy on the bifurcation diagram and the decay rates is discussed.
Spontaneous isotropization of the condensates is found to occur. The influence
of isotropization on the decay rates is characterized near the critical point.
