Isobars are atoms of different chemical elements that have the same number of nucleons. Correspondingly, isobars differ in atomic number (or number of protons ) but have the same mass number . An example of a series of isobars is 40 S , 40 Cl , 40 Ar , 40 K , and 40 Ca .

Isobars are nuclides having the same mass number (i.e. sum of protons plus neutrons): e.g. carbon-12 and boron-12. Nuclear isomers are different excited states of the same type of nucleus. A transition from one isomer to another is accompanied by emission or absorption of a gamma ray, or the process of internal conversion.
Isobar may refer to: Isobar (meteorology), a line connecting points of equal atmospheric pressure reduced to sea level on the maps. Isobaric process, a process taking place at constant pressure; Isobar (nuclide), one of multiple nuclides with the same mass but with different numbers of protons (or, equivalently, different numbers of neutrons).
Units of activity (the curie and the becquerel) also refer to a quantity of radioactive atoms. Because the probability of decay is a fixed physical quantity, for a known number of atoms of a particular radionuclide, a predictable number will decay in a given time.
In physics, mirror nuclei are a pair of isobars of two different elements where the number of protons of isobar one (Z 1) equals the number of neutrons of isobar two (N 2) and the number of protons of isotope two (Z 2) equals the number of neutrons in isotope one (N 1); in short: Z 1 = N 2 and Z 2 = N 1.

Beta radiation from linac accelerators is far more energetic and penetrating than natural beta radiation. It is sometimes used therapeutically in radiotherapy to treat superficial tumors. Beta-plus (β +) radiation is the emission of positrons, which are the antimatter form of electrons. When a positron slows to speeds similar to those of ...
