 Abstract: Near the black hole threshold in phase space, the black hole mass as a function of the initial data shows the “critical scaling” M≃C(p-p*)γ, where p labels a family of initial data, p* is the value of p at the threshold, and the critical exponent γ is universal for a given matter model. The black hole charge Q obeys a similar law. To complete the picture, we include the angular momentum as a perturbation. For the black hole angular momentum L→, we find the oscillating behavior L→≃Re[(A→+iB→)(p-p*)μ+iω]. The assumptions of the calculation hold for p=ρ/3 perfect fluid matter, and we calculate μ≃0.799 and ω≃0.231.
