Query: Particle Creation in the Marginally Bound, Self Similar Collapse of
  Inhomogeneous Dust   We consider the evaporation of the (shell focusing) naked singularity formed
during the self-similar collapse of a marginally bound inhomogeneous dust
cloud, in the geometric optics approximation. We show that, neglecting the back
reaction of the spacetime, the radiation on $\scrip$ tends to infinity as the
Cauchy Horizon is approached. Two consequences can be expected from this
result: (a) that the back reaction of spacetime will be large and eventually
halt the formation of a naked singularity thus preserving the Cosmic Censorship
Hypothesis and (b) matter attempting to collapse into a naked singularity will
radiate away energy at an intense rate, thereby possibly providing experimental
signatures of quantum effects in curved spacetimes.
