characteristics and you will make a Fermi-Kurie plot of the Na22 beta spectrum to demonstrate Fermi's theory of beta decay and confirm the small mass of the.

Electron Capture in the Decay of Na. 22.

Alpha Emission. Alpha \(\left( \alpha \right)\) decay involves the release of helium ions from the nucleus of an atom. This ion consists of two protons and two neutrons and has a \(2+\) charge. Release of an \(\alpha\)-particle produces a new atom that has an atomic number two less than the original atom and an atomic weight that is four less. 1 Decay Scheme Am-241 decays 100% by alpha transitions to Np-237.

annihilation gamma This is a special spectrum, it was taken with PRA 5.0 using two sodium iodide detectors, in coincidence counting mode, to detect the annihilation gammas that are produced when 22Na undergoes beta+ decay. The positron instantly annihilates with an electron, producing two 511 keV gammas at a 180˚ angle.
