beta decay betydelse and definition

Exempel på beta decay

• The usual radioactive decay, the beta decay, is the best-known example of a so-called weak interaction.

• Er, is electron capture, and the primary mode after is beta decay.

• U-239 rapidly undergoes beta decay to form neptunium-239, which rapidly undergoes a second beta decay to form plutonium-239.

• The gadolinium quickly captured the neutrons produced in the inverse beta decay.

• Ag, is electron capture and the primary mode after is beta decay.

• The electrostatic force is almost always significant, and, in the case of beta decay, the weak nuclear force is also involved.

• Potassium-40 is a rare example of an isotope that undergoes all three types of beta decay.

• This is in apparent contradiction to the law of conservation of energy, as it appeared that energy was lost in the beta decay process.
