In this Letter, we evaluate the radial and axial square radii (effective widths) of a rapidly rotating boson gas. The corresponding effective area and the expansion energy are calculated from these effective widths. A modified semiclassical approximation is suggested. This approach provides significant corrections to these quantities, such as finite size effect and indirectly interaction effect. We show that the effective widths still follow a non-rotating temperature dependence. Rotation leads to expansion or shrinking the effective widths through the change of the harmonic frequencies of the confinement trap.
► In the present Letter the effective widths for rotating boson gas in harmonic trap are investigated.
► The corresponding effective area and expansion energy are extracted.
► The main effects, such as finite size, and inter-atomic interaction, are considered simultaneously.
► The above mentioned parameters exhibit a characteristic rotation rate dependence.
