Test cases included in the source

Three test cases are included in the empire/TESTS directory that is a part of the standard EMPIRE distribution (empire-2-19b24.tgz file). These are relatively simple and fast calculations and only most relevant outputs are provided. Copies of input files are stored in the empire/test directory ready for being run. The three cases are:

  n_Mo100.inp - typical interaction of neutron with 100-Mo at 14 MeV using Coupled Channels, MSD, MSC, and two exciton models (DEGAS for gammas and PCROSS for protons and alphas).

  a_Ni58.inp - alpha induced reaction on 58-Ni at incident energy of 40 MeV showing ability of EMPIRE to use DWBA model for alpha-projectile and preequilibrium emission of clusters (PCROSS).

  48Ca_208Pb.inp - 48-Ca incident on 208-Pb target at 205 MeV following emission of 2 neutrons.

Test cases

Three test cases are included below in order to test EMPIRE installation and to provide a brief introduction to the use of the code. They illustrate basic features only and do not address variety of possible options. Each test case is given as a tarred and gzipped file (.tgz) containing input and all output files created during the run. When downloaded and saved in the empire directory these files should be untarred and uncompressed with the command:

tar xvzf 'test_case_name'.tgz

This will create a number of files in the empire/work directory, which can be viewed using GUI after an appropriate test_case_name (without extension) is introduced into the GUI 'Project' field. Note that running calculations will overwrite output files. Therefore, the related input files are also included in the empire/test directory in which they can be safely run and compared to those stored in the empire/work.

• eu153dir.tgz - Coupled Channel (CC) calculations of inelastic scattering and (n,g) reaction on 153-Eu at incident energy of 1 MeV using RIPL optical model potentials (omp). Note that CC #2004 omp is used for total, elastic, and inelastic scattering calculations with ECIS (DIRPOT=-2004 option in the input) while spherical RIPL omp #221 (OMPOT=-221 option in the input) is used for the calculation of all neutron transmission coefficients. This is consistent with the DIRECT=1 option selected in the input. Use of the CC omp in all neutron channels would require lengthy DIRECT=2 option.
• eu153preq.tgz - Calculations of neutron induced reactions on 153-Eu at 14 MeV using combined MSD, MSC, Exciton and HF models.
• nb93.tgz (14 Mb!) - Full calculations of neutron induced reactions on 93-Nb in the energy range from 0.001 to 27 MeV using combined MSD, MSC, Exciton and HF models. This test case includes ENDF formatting and plots comparing theoretical predictions with experimental results.
