where [q.sub.P] = 1.6 x [10.sup.-19] C is the charge on the proton, [[epsilon].sub.0] = 8.85 x [10.sup.-12] [m.sup.-3][kg.sup.-1][s.sup.4][A.sup.2] is the permittivity of free space and d is the distance between the deuterons. Overcoming the Coulomb barrier between the two deuterons in this process usually requires a high momentum and therefore temperatures in excess of 100 MK which are thought to only be possible in gravitationally-confined systems such as the Sun or magnetically-confined fusion reactors.
Subatomic particles such as neutron, proton, deuteron, [sup.3]He, [sup.4]He, and other heavier particles are generated and then accelerated to certain energies sufficient for production of radioisotopes.
If the material of the NPs cannot be activated by proton irradiation, other accelerated ions might be used, that is, deuterons. Deuteron irradiation was used to create [sup.141]Ce-labeled NPs via the (d, p) reaction from [sup.140]Ce .
This is a sensational contradiction of QM because it circumvents the argument that a particle-like split, such as splitting into two deuterons, is somehow still at play.
The first theoretical enigma I faced was the necessity of overcoming the Coulomb barrier between two deuterons (deuterium nuclei).
At energies above 10 keV this is reasonable since stopping power has been measured for protons, deuterons and tritons and the results are the same for equal velocities (7).
The resulting neutron can combine with another proton to form a composite particle known as a deuteron. These deuterons "burn" via a thermonuclear reaction, and this provides the intense heat and brilliant light of the sun.
To sort out what was happening, the RHIC teams turned to the less energetic collisions between gold ions and deuterons. If gluon saturation were at work, jet suppression would persist at these lower energies.
The instrument in use here was the 60-inch cyclotron, and the diamonds were bombarded with neutrons and alpha particles, as well as deuterons. The results were informally reported in an article in Gems and Gemology (Ehrmann, 1950), and more formally in the American Mineralogist (Hamilton et al., 1952).
In 1937 Segre bombarded molybdenum with deuterons, the atomic nuclei of hydrogen-2, which had been discovered by Urey (see 1931, Deuterium).
* corpuscular radiation such as alpha- and beta-radiation, high energy electrons, protons, deuterons and neutrons.
The PHENIX experiment calculates charged average [v.sub.2] of (anti) deuterons as
Before he and his colleagues were given the task to create a high-voltage generator according to the known scheme Cockcroft-Walton  to accelerate deuterons D (nuclei of hydrogen isotopes-deuterium [sub.1.sup.2]H) to energy of 200 keV .
