Higgs's subsequent 1966 paper showed the decay mechanism of the boson; only a massive boson can decay and the decays can prove the mechanism.

This excitation also triggers various decay mechanisms.

The lattice reduces the lifetime of the excited state by introducing radiationless decay mechanisms.

Exponential decay mechanism:

Negated-translated sigmoid decay mechanism:

As the graph approaches 0, it represents how the memory is being forgotten using decay mechanisms.

Besides radiative decay, which occurs under the emission of light, there is a second decay mechanism; nonradiative decay.

These last two decay mechanisms compete with stimulated emission reducing the efficiency of light amplification.

The existence of this decay mechanism has been proven experimentally in Argon dimers and in mixed Argon - Krypton clusters.

The detailed decay mechanism is electron capture to form the nearly-stable nuclide tellurium-125.
