Bromine-77 is the most stable radioisotope of bromine, with a half-life of 57 hours. [13] Although β + decay is possible for this isotope, about 99.3% of decays are by electron capture. [ 9 ] Despite its complex emission spectrum, featuring strong gamma-ray emissions at 239, 297, 521, and 579 keV, [ 14 ] 77 Br was used in SPECT imaging in the ...
This page uses the meta infobox {{Infobox isotopes (meta)}} for the element isotopes infobox.. This infobox contains the table of § Main isotopes, and the § Standard atomic weight.
No isotopes known, Isobox does not exist: local input, per Infobox. For example: Transclusion of the isobox is suppressed (no redlink), E119: |theoretical isotopes comment=Experiments and theoretical calculations Applied: E119 and up: have no Isobox, so no isotopes lists is shown—at all. Instead, the parametertext is shown as present.
An isochron diagram will only give a valid age if all samples are cogenetic, which means they have the same initial isotopic composition (that is, the rocks are from the same unit, the minerals are from the same rock, etc.), all samples have the same initial isotopic composition (at t 0), and the system has remained closed.

Isotope peaks within a spectrum can help in structure elucidation. Compounds containing halogens (especially chlorine and bromine) can produce very distinct isotope peaks. The mass spectrum of methylbromide has two prominent peaks of equal intensity at m/z 94 (M) and 96 (M+2) and then two more at 79 and 81 belonging to the bromine fragment.
Other bromine isotopes are all radioactive, with half-lives too short to occur in nature. Of these, the most important are 80 Br ( t 1/2 = 17.7 min), 80m Br ( t 1/2 = 4.421 h), and 82 Br ( t 1/2 = 35.28 h), which may be produced from the neutron activation of natural bromine. [ 31 ]
This template is used in the articles for superheavy elements to produce the sortable lists of isotopes. It was created to simplify formatting and standardize references. For each isotope, a row {{isotopes summary/isotope}} is to be added. The template {} is required on any pages that use this template.
