Member Function Documentation

◆ atomic_target()

virtual marley::TargetAtom marley::ElectronReaction::atomic_target ( ) const

inlinefinaloverridevirtual

Returns the target atom involved in this reaction.

For nuclear reactions, this is identical to the pdg_b_ member variable. For electron reactions, it is distinct (since particle b is the initial struck electron).

Implements marley::Reaction.

◆ create_event()

marley::Event marley::ElectronReaction::create_event	(	int	pdg_a,
		double	KEa,
		marley::Generator &	gen
	)		const

overridevirtual

Create an event object for this reaction.

Parameters

pdg_a	PDG code for the incident projectile
KEa	Lab-frame kinetic energy of the projectile
gen	Reference to the Generator to use for random sampling

Note: Functions that override create_event() should throw an Error if pdg_a != pdg_a_.

Implements marley::Reaction.

◆ diff_xs()

double marley::ElectronReaction::diff_xs	(	int	pdg_a,
		double	KEa,
		double	cos_theta_c_cm
	)		const

overridevirtual

Differential cross section \(d\sigma/d\cos\theta_{c}^{\mathrm{CM}}\) (MeV^-2)

Parameters

pdg_a	PDG code for the projectile
KEa	Lab-frame kinetic energy (MeV) of the projectile
cos_theta_c_cm	CM frame scattering cosine of the ejectile

Note: Functions that override diff_xs() should always return zero if pdg_a != pdg_a_.

Todo:: Take into account effects of electron binding energy

Implements marley::Reaction.

◆ total_xs()

double marley::ElectronReaction::total_xs	(	int	pdg_a,
		double	KEa
	)		const

overridevirtual

Compute the reaction's total cross section (MeV^-2)

Parameters

pdg_a	Projectile's PDG code
KEa	Lab-frame kinetic energy of the incident projectile

Returns: Reaction total cross section (MeV^-2)

Note: Functions that override total_xs() should always return zero if pdg_a != pdg_a_.

Todo:: Take into account effects of electron binding energy

Implements marley::Reaction.
