Abstract: We study stable rank two algebraic vector bundles on $ {{\mathbf{P}}^3}$ and show that the family of bundles with fixed Chern classes and spectrum may have more than one irreducible component. We also produce a component where the generic bundle has a monad with ghost terms which cannot be deformed away.
