Beta Decay Q Value Calculator

Formula

The formula to calculate the Beta Decay Q Value (Q) is:

$Q = (M_p - M_d) \cdot 931.494$

Where:

Beta Decay Q Value (Q): The energy released during beta decay, measured in MeV.
Mass of the Parent Nucleus (M_p): The mass of the nucleus before beta decay, measured in atomic mass units (u).
Mass of the Daughter Nucleus (M_d): The mass of the nucleus after beta decay, measured in atomic mass units (u).
Significance: The Q value is important in nuclear physics as it indicates the energy released during the decay process.

Let's say the mass of the parent nucleus (M_p) is 14.0031 u and the mass of the daughter nucleus (M_d) is 14.0030 u. Using the formula:

$Q = (14.0031 - 14.0030) \cdot 931.494 = 0.0001 \cdot 931.494 = 0.0931$

So, the beta decay Q value is 0.0931 MeV.
