Matter and Interactions
P.32 An alpha particle (a helium nucleus, containing 2 protons and 2 neutrons)
starts out with kinetic energy of 10 MeV (10 × 106 eV), and heads in the +x
direction straight toward a gold nucleus (containing 79 protons and 118 neutrons
).
Ruth W. Chabay, Bruce A. Sherwood, 2011

Radioactivity: Introduction and History: Introduction and ...
The nuclei of daughter atoms of alpha-particle-emitting nuclides are often
unstable themselves and may also decay by further alpha-particle emission.
Thus, alpha-particle-emitting nuclides may consist of a mixture of radionuclides,
all part of a ...

Magnet power supply for
alpha-
particle spectrometer II
A current regulated power supply has been built to deliver current, continuously variable from 0 to 600 ma, into a load of 4000 ohms. The system is stable to approximately 1 part in 10,000 over long periods of time.
George F. Schrader, University of California, Berkeley. Radiation Laboratory, 1956

(Helium nucleus) (4.00147 amu) Parent nucleus Am-241 U-238 Th-232 FiGuRe
19.1 Alpha decay. An alpha particle can also be thought of as a fully ionized ...
According to the principles of the conservation of energy and the conservation of
momentum, this energy is shared between the alpha particle and the recoiling
daughter nucleus — particles that have equal and opposite momenta. The
emitted ...

General, Organic, and Biological Chemistry
11.34 Platinum-192 decays to osmium-188 through alpha particle emission.
Based on the following diagram, in which yellow spheres represent platinum-192
nuclides and red spheres represent osmium-188 nuclides, how many halflives
have ...

BiCMOS Technology and Applications
When an alpha particle strikes silicon, it travels and loses energy along a straight
path. The length of travel depends on the energy of the alpha particle. The
energy lost by the incident particle goes to create high energy electron-hole (e-h)

“The detrimental radiolytic effects described above have greatly complicated the
synthesis of .alpha.-particle emitter labeled pharmaceuticals having
therapeutically effective levels of radioactivity. This is especially true in cases
where it is ...

The
Particle Odyssey : A Journey to the Heart of the Matter: ...
This makes an exceptionally stable configuration; in fact, it is the nucleus of
helium – the alpha particle. The stability of alpha particles accounts for their
appearance in radioactive decays, particularly of heavy elements such as
uranium and ...

Field Studies of Radon in Rocks, Soils, and Water
The gross alpha-particle activity generally indicates the total amount of uranium
and 226Ra present in the sample; this was true of ground waters in the Newark
basin. The combined activities of uranium and 226Ra equaled, or nearly equaled
, ...
