title: Radiation from a nonisothermal spherical cavity: an exact solution.
abstract: A numerical solution is given for the radiation intensity from a spherical cavity whose spatial temperature and emissivity are both arbitrary. This simplifies and clarifies previous research. A numerical example with large axial temperature gradient is given, and it is suggested that this analysis could help establish the spherical cavity as a radiation standard.
