These are hydrogen atoms with an extra electron, which are also formed when the gas, originally in the form of molecules of two atoms, is ionized.

This article reviews the theoretical basis for expecting the presence of carbon-14 in Pliocene to Cambrian carbon from certain creationist viewpoints, and for expecting its absence from a viewpoint proposing a long age of life on Earth. Several conclusions emerge: 1) There is measurable carbon-14 in material that should be "dead" according to standard evolutionary theory; 2) machine error can be eliminated as an explanation for this carbon-14 on experimental grounds; 3) nuclear synthesis of this carbon-14 in situ can be eliminated on theoretical grounds; 4) contamination of fossil material in situ is unlikely but theoretically possible, and is a testable hypothesis; 5) contamination during sample preparation is a significant problem but theoretically soluble; 6) residual activity is most likely indicated by the present data, and if correct, would eliminate an age greater than approximately 100,000 years for life on Earth; and 7) additional experimental evidence cannot eliminate either a short or a long age of life on Earth, but can provide evidence tending to discriminate between the two.

Nuclear medicine uses radiation to provide information about the functioning of a person's specific organs, or to treat disease.

In some cases radiation can be used to treat diseased organs, or tumours.

Solution: Cyclotrons are sometimes used for carbon-dating by accelerating singly ionized C14 and C12 ions from a sample of material.

The attributes of naturally decaying atoms, known as radioisotopes, give rise to several applications across many aspects of modern day life (see also information paper on The Many Uses of Nuclear Technology).

Finally, all accelerators must have some means of detecting, counting, and measuring the particles after they have been accelerated through the Electrons and protons, the particles most commonly used in accelerators, are found in all materials, but for an accelerator the appropriate particles must be separated out.

Electrons are usually produced in exactly the same way as in a television picture tube, in a device known as an (positive electrode), where they pass through a hole.

If the cyclotron has a magnetic field of magnitude 2.80 T, what is the difference in cyclotron frequencies for the two ions?
