SCAT-2 is designed as a fast, easy-to-use program to calculate total cross sections, elastic scattering cross sections and their angular distributions, and transmission coefficients from the optical model of a spherical nucleus. SCAT-2B extends the incident particles to include heavy ions. The distribution CD includes both SCAT-2 (P00294MNYCP03) and SCAT-2B (P00294MNYCP02).
The calculation is performed at a specified set of energies for one of the following incident particles: neutron, proton, deuteron, triton, helium-3, helium-4 or alpha, heavy ions. The nuclear potential contains the following terms: Coulomb, a real volume Woods-Saxon potential, an imaginary surface Woods-Saxon or Gaussian potential, an imaginary volume Woods-Saxon potential, and a spin-orbit potential. A partial wave expansion of the Schrödinger equation is numerically integrated using Cowell's method.
The optical potential of SCAT-2 (2010 version) has been extended to include an imaginary spin-orbit component and the Koning-Delaroche optical model parameterization has been incorporated.
SCAT-2: The maximum number of input energies was increased from 50 to 150.
SCAT-2B: A maximum of 50 incident particle energies can be specified.
SCAT-2 was tested at RSICC on a Pentium PC running Windows XP™ . Running time was about a second for the SCAT-2B sample problem which was run at RSICC on an IBM RS/6000 and a Pentium 4.
SCAT-2 runs on PCs – Windows and Linux. SCAT-2B runs on workstations and Pentium computers.
The SCAT-2 (P00294MNYCP03) code was written in Fortran 77. RSICC used the Lahey Fortran 7.10 and DVF 6.6c compilers under the Windows XP operating system, and g77 on Linux Ubuntu 10.04.
The SCAT-2B (P00294MNYCP02) source code was written in Fortran 77 and was tested at RSICC on an IBM RS/6000 Model 270 running AIX 4.3.3 with xlf Fortran 7.1 and on a Pentium 4 in a DOS window of Windows2000 with the Digital Visual Fortran 6.0 compiler. The DVF executable was added to the package. This release was also tested at the NEA Data Bank under Linux with the g77 compiler.
Note that no new documentation is available for the SCAT-2B package.

Informal notes.
Included are the referenced documents and one CD with self-extracting compressed Windows files which include Fortran source, PC executables, and sample case input and output for both SCAT-2 (P00294/MNYCP/03) and SCAT-2B (P00294/MNYCP/02).
