◆ QValueDoubleElectronCaptureInJ()

template<typename T >
T EGXPhys::QValueDoubleElectronCaptureInJ ( const T  massParentInu,
const T  massDaughterInu,
const T  neutronBindingEnergyInJ = (T)(0.0) 
)

Calculates the Q-value, \(Q\), of a double electron capture(k-capture) nuclear reaction in joules. The Q-value allows you to determine if a nuclear reaction is endothermic or exothermic.

The Q-value, \(Q\), is the energy released during a nuclear reaction. The Q-value can be positive, negative or zero. For \(Q < 0\) the reaction is endothermic/endoergic resulting in the kinetic energy of the reaction being converted into mass or binding energy. For \(Q > 0\) the reaction is exothermic/exoergic resulting in the mass or binding energy being released as kinetic energy.

To calculate the Q-value it is the initial mass of the parent atom, \(m(\ce{ ^{A}_{Z}X_{N} })\), minus the final mass of the daughter atom, \(m(\ce{ ^{A}_{Z -2}Y_{N +2} })\), as well as the binding energy of the n-shell captured electron \(B_{2n}\):

\[Q = \left ( m(\ce{ ^{A}_{Z}X_{N} })-m(\ce{ ^{A}_{Z -2}Y_{N +2} }) \right) c^2-B_{2n}\]

Depending on the database/calculation style the binding energy of the n-shelled captured electron is not included in the calculation. For example nndc.bnl.gov exlcudes it while Krane includes it.
