Abstract
We calculate the energy and condensate fraction for a dense system of bosons interacting through an attractive short range interaction with positive -wave scattering length . At high densities , the energy per particle, chemical potential, and square of the sound speed are independent of the scattering length and proportional to , as in Fermi systems. The condensate is quenched at densities .
