fragment_emission_threshold()

double marley::MassTable::fragment_emission_threshold	(	const int	Zi,
		const int	Ai,
		const marley::Fragment &	f
	)		const

Get the approximate excitation energy threshold for emission of a particular nuclear fragment.

Parameters

Get the mass of an atom.

Parameters

Z	Atomic number of the atom
A	Mass number of the atom
theory_ok	Whether to calculate a theoretical mass using the liquid drop model if an experimental mass cannot be found. If theory_ok is false, then a marley::Error will be thrown if an experimental mass cannot be found.

Returns

Atomic mass (MeV)

get_binding_energy()

Parameters

Z	Atomic number
A	Mass number
theory_ok	Whether to use a theoretical (liquid drop model) atomic mass during the calculation if an experimental atomic mass cannot be found. If theory_ok is false, then a marley::Error will be thrown if an experimental atomic mass cannot be found.
