ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

The spherical harmonics (PN) solution at the surface of a source-free half-space is investigated to determine conditions for which exact results can be obtained with an approximation of any odd order N. For isotropic scattering, an exact solution for the net current can be obtained if the incident illumination comes from an isotropic plane source, which extends the observation of Garcia and Siewert that an exact solution for the scalar flux can be obtained if the incident illumination is constant with the cosine of the polar angle. An exact solution for the scalar flux at the interface between two isotropic-scattering, half-space media also can be obtained with a finite N for a spatially uniform source in one half-space.
