  The potential sub-shell closures N = 32 and N = 34 are analyzed at high spins
in the titanium isotopes within the generalized beyond mean field theory
considering triaxial deformations and the angular frequency as generator
coordinates together with the particle number and the angular momentum
conservation. A good description of bulk properties, high angular momenta
spectra and transition probabilities is obtained. The outcome at high spin in
these nuclei is consistent with the magic number character of N = 32 but not of
N = 34.
