Detailed Description

Modules are run using calculated atomic wavefunctions.

After the pogram has generated wavefunctions (Hartree-Fock etc), any number of modules can then be run (see input documentation for how to run them). Examples include: calculating matrix elements, lifetimes, PNC etc.

To add a new module:

Function Documentation

◆ calculatePNC()

void Module::calculatePNC ( const IO::InputBlock input,
const Wavefunction wf 
)

Calculates E1 PNC amplitude.

Uses both 'solving equations' (TDHF) and sum-over-states methods. For solving equations, calculates both:

  • <yA_w|d| B> + <A |d|xB_w>
  • <A |w|XB_d> + <YA_d|w| B>
  • Does not (yet) include DCP

Allowed inputs:

Module::pnc{ c; t; transition; rpa; omega; nmain; }

  • c, t: half-density radius and skin-thickness (in fm) for rho(r). Will look up default values by default.
  • transition: For E1_PNC a->b transition.
    • in form "a,b", uses the 'short' notation:
    • e.g., "6s+,7s+" for 6s_1/2 -> 7s_1/2
    • e.g., "6s+,5d-" for 6s_1/2 -> 5d_3/2
  • rpa: true/false. Include RPA or not (TDHF ,method)
  • omega: frequency used for RPA (default is transition frequency of valence).
  • nmain: highest n (prin. q. number) considered as part of 'main'.
    • If not given, will be max(n_core)+4
    • (Calculation broken into core, main, tail)

◆ Kionisation()

void Module::Kionisation ( const IO::InputBlock input,
const Wavefunction wf 
)

Calculates atomic ionisation factor, Kion(E,q) = |<a|j_L|e>|^2, summed over core states, where E is deposited energy: E = |E_a| + e.

◆ polarisability()

void Module::polarisability ( const IO::InputBlock input,
const Wavefunction wf 
)

Calculate atomic (dipole) polarisability, alpha, at given frequency.

  • J. Mitroy, M. S. Safronova, and C. W. Clark, Theory and Applications of Atomic and Ionic Polarizabilities, J. Phys. B 43, 44 (2010).

◆ structureRad()

void Module::structureRad ( const IO::InputBlock input,
const Wavefunction wf 
)

Calculates Structure Radiation + Normalisation of States.

Note: Most input options are similar to MatrixElements module:

Module::structureRad{ operator; options; rpa; printBoth; onlyDiagonal; omega; n_minmax; }

n_minmax: is input as list of ints: n_minmax = min,max; min: minimum n for core states kept in summations max: maximum n for excited states kept in summations

For explanation of the rest, see MatrixElements module.

◆ tests()

void Module::tests ( const IO::InputBlock input,
const Wavefunction wf 
)

A range of run-time tests (orthonorm, <H>, sum rules etc.) – see input options.

Note: These are run-time tests to ensure input params were OK, not unit tests! (see unitTests.cpp for unit tests)
