Everything CCEA students need to know about radioactive decay and half-life for GCSE Physics.

An unstable nucleus can decay by emitting an alpha particle, a beta particle, or a gamma ray. Alpha particle. An unstable nucleus can emit a ‘package’ of two protons and two neutrons, ...

Alpha particles, also known as alpha radiation, are the star players in the game of alpha decay — here's everything you need to know.

Today, normal service returns with a report on the decay rates inside a metal host of ruthenium-97 by electron capture and ruthenium-103 and rhodium-105, both by beta(-) emission.

The largest decays are for inverse leveraged ETFs in Energy (ERY) and Emerging Markets (EDZ), with a drift about -0.8% normalized to 1x the underlying index exposure. The highest positive drift is ...

The scientists registered 128 alpha-particle events over 5 days and found an unexpected line in the spectrum at 3.14 MeV – now attributed to bismuth-209 decay. The half-life was calculated to be (1.9 ...

And 0.04% is the volatility decay. Second, leverage ETFs suffer volatility decay more severely. Following the above example, the 3x leveraged UPRO would go up 6% on day 1 and go down 6% on day 2.
