(1 Mar 2000)
MCNP4C was released 29 February 2000
and was sent to the RSICC for distribution.

The principal new MCNP4C features are:

* Unresolved resonance range probability tables;
* Alpha eigenvalue search;
* Perturbation enhancements;
* Superimposed importance meshes;
* Macrobodies;
* PC enhancements;
* ENDF/B-VI improvements;
* Electron physics enhancements;
* Parallel enhancements;
* Delayed neutrons;
* Cumulative tallies.

Macrobodies are body surfaces such as BOX, RPP, SPH, RCC, RHP, HEX that mimic the combinatorial geometry of other codes such as the Integrated Tiger Series. They can be used in combination with regular MCNP surfaces to greatly simplify geometry specification.

Superimposed importance meshes enable you to describe a geometry without having to subdivide the geometry for variance reduction; variance reduction is done on the superimposed mesh.

PC enhancements include Lahey FORTRAN90 and DEC Visual Fortran 90 with XLIB graphics.
