Items under development

The next release of the SAMMY code and users' manual is expected to become available in 2006. Features which have been developed and incorporated into the new version include (but are not limited to) the following items:

  • 1. Additional improvements to the treatment of the URR (Unresolved Resonance Region)

  • 2. A (numerical) user-defined resolution function

  • 3. Crystal-lattice model for Doppler broadening

  • 4. Resolution functions appropriate for use with data from GELINA and from nTOF (extension of the RPI resolution function)

  • 5. Expanded capability for interfacing with ENDF Files 2, 3, 32, 33

  • 6. Significant new developments for easy and accurate treatment of data covariance matrices

    a. User-supplied pieces of the data covariance matrix
    b. Simple methods for inclusion of uncertainties on data-related parameters as contributors to the data covariance matrix (PUP = Propagated Uncertainty Parameters)
