Abstract
We study the critical behaviour of spherically symmetric scalar field collapse to black holes in spacetime dimensions other than four. We obtain reliable values for the scaling exponent in the supercritical region for dimensions in the range 3.5 ⩽ D ⩽ 14. The critical exponent increases monotonically to an asymptotic value at large D of γ ∼ 0.467. The data are well fit by a simple exponential of the form γ ∼ 0.467(1 − e−0.408D).
