DWBA Analysis Companion

  • Simple to use Fresco Manager
  • Uses FRESCO template files and neutron state information to generate a DWBA calculation and fit it to data to extract experimental spectroscopic factors
  • Can also be used to generate elastic scattering files to normalize data to DWBA

Calculate Mode

  • Calculates DWBA angular distributions by generating an input file from basic user input, or from existing .frin file

Search Mode

  • Calculates SF for all possible neutron states and returns lowest chi2 fit

Scan Mode

  • Calculates SF & Sig for all possible neutron states and produces a graphs of these values as a function of ExcHi and fits this to a cumulative function which indicates the best SF.

Description of variables

  • REAC - "dp", "dt", "pp", "dd" selects the reaction

** neutron state information **

  • EXC - Excitation energy [MeV]
  • BE - Binding energy of neutron [MeV]
  • JF - Total angular momentum of final state, coupling [s1/2][nlj]
  • J0 - Total angular momentum of orbital that neutron is placed in
  • L0 - Orbital angular momentum of orbital that neutron is placed in
  • N0 - Principal quantum number of orbital that neutron is placed in
  • SF - Spectroscopic Factor
  • CS - Total cross section [with SF appplied]

** required to determine spectroscopic factor error **

  • NORM - Normalization Used
  • GAM - Gamma gate used

** these are taken from the Results_Exc.root file **

  • ExcHi - Upper excitation energy window, see ScanEnergyWindow
