Abstract
The coordinate-space variational treatment for the hard-sphere boson gas developed by Aviles and Iwamoto has been extended to include the first logarithmic term in the ground-state energy expansion. The result agrees, within four percent, with the exact results of Wu and others. The form of the variational wave function used is discussed and compared with that obtained using the pseudopotential method of Lee, Huang, and Yang.
