The half-life of this alpha decay was first measured as 150 days and then corrected to 162.8 days.

Small amounts of helium are also present in pitchblend as a result of alpha decay.

The daughter nuclide of an alpha decay is an isodiapher of the original nucleus.

The process of alpha decay may be thought of as a special type of spontaneous nuclear fission.

Perey then attempted to determine the proportion of beta decay to alpha decay in actinium-227.

The process of alpha decay is in essence a special type of spontaneous nuclear fission.

He discovered a theoretical explanation of alpha decay through quantum tunneling.

Thus it is the only promethium isotope with an experimentally observed alpha decay.

Np is the product of alpha decay of Am.

Many helium-4 on Earth is produced from alpha decay of heavy elements.
