Electron-impact excitation of Mn V

The file omegau contains (unformatted) collision strengths for electron-impact excitations among 200 fine-struture levels in Mn V, evaluated at 92,601 incident electron energies between 0 and 9 rydbergs. The code xtrct.f extracts collision strengths from the file omegau. When run, the user is prompted to input the lower and upper indices (I and J, respectively) and of a transition. The output file, xout, contains four columns: Column 1: Incident electron energy (in rydbergs) relative to the ground state of the N-electron system. Column 2: Incident electron energy (in rydbergs) relative to the initial N-electron state of the transition. Column 3: Incident electron energy (in rydbergs) relative to the final N-electron state of the transition. Column 4: Collision strength for the electron-impact excitation from state I to state J of the N-electron system.
