Abstract
A method based on the Euler-Maclaurin formula is proposed to obtain all finite-size corrections to the energies of the ground and excited states for the one-dimensional Bose gas with delta function interactions. Scaling dimensions for all gapless states and some states having a macroscopic momentum are obtained.Keywords
