Scientists taking part in ALPHA include former members of the ATHENA experiment (AD-1), the first to produce cold antihydrogen in 2002. On 27 September 2023, ALPHA collaborators published findings suggesting that antimatter interacts with gravity in a way similar to regular matter, supporting a prediction of the weak equivalence principle .
Alpha spectrometry (also known as alpha(-particle) spectroscopy) is the quantitative study of the energy of alpha particles emitted by a radioactive nuclide that is an alpha emitter. As emitted alpha particles are mono-energetic (i.e. not emitted with a spectrum of energies, such as beta decay ) with energies often distinct to the decay they ...

Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science.Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
In 2022, Curtin Singapore moved onto levels 1 through to 4 of the Alpha building in Singapore Science Park 2. [67] Co-located with industry within the science park precinct, Curtin Singapore is a 15-minute walk from Haw Par Villa MRT station and is closer to NUS, the National University Hospital and the Greater Southern Waterfront.

With the Alpha acquisition, EnerSys expanded its portfolio to become a fully integrated DC power and energy storage system and technology provider for broadband, telecom and energy storage systems. Outdoor equipment enclosure products are utilized in the telecommunication, cable, utility, and transportation industries, as well as by government ...
This makes it possible to calculate the mass of the nucleus hit by the alpha particle. Light elements absorb more energy of the alpha particle, while alpha particles are reflected by heavy nuclei nearly with the same energy. The energy spectrum of the scattered alpha particle shows peaks from 25% up to nearly 100% of the initial alpha particles.
