    Abstract

    We investigate natural supercoherent approximations to an otherwise exact representation of the ground state of an anharmonic oscillator. The truncated wavefunctions are neither normalisable nor unique. Quite different such wavefunctions can give very accurate estimates for the energy eigenvalue, which are always finite. Possible parallels in quantum optics are drawn.
