I've seen a different nuclide map (I suppose the difference is whether elements with astronomical half-lives are considered stable or radioactive) where an isotope has the complementary property: it is unstable whereas its eight neighbours are stable.

Yeah, JAEA, which calls U235 stable, says Indium 114. The Brookhaven tables say three of the eight are (very slightly) unstable. Given the astronomical pace of intranuclear fidgetings, how do they count up to a quintillion, let alone quintillions times the internal clock rate times picoseconds in a year? --rwg On 2015-07-28 16:38, Adam P.

Amongst isobars (nuclei of constant mass number) with odd mass, there is one possessing minimum mass and is the most stable. Nuclei with more neutrons beta decay by electron emission toward that stable isotope, while nuclei with more protons decay by electron capture or positron emission. In the Chart, such nuclei lie on a line with 135 degree slope. If you can find an example with more than one beta stable odd mass isotope along such a line, I'd like to know about it. For even mass isobars, the situation is more complicated. Even-even isotopes are more stable than odd-odd isotopes. It is possible to have more than one local minimum. For example, Sn-124, Te-124, and Xe-124 are all stable. In such cases, double beta decay towards the global minimum by emission of 2 electrons together with 2 antineutrinos is allowed, but highly suppressed by the need for two simultaneous weak interactions. Some favorable cases have half-lives short enough to be measurable: Se-82 (1e20 y), Cd-116 (3e19 y), Mo-100 (7e18 y). See the Wiki for a more complete list. https://en.wikipedia.org/wiki/Double_beta_decay The spin of a neutrino is antiparallel to its momentum, but for an antineutrino the spin is parallel to the momentum. (I hope I got that that right. In any case, one is parallel, the other antiparallel.) If neutrinos were massless, that relation would be Lorentz invariant. But since neutrinos do have mass, it is possible to go fast enough to overtake one, and then the momentum changes sign. Does the, normally left-handed, neutrino become a right-handed neutrino, with interactions even weaker than the usual weak interaction, or does it turn into an antineutrino? We don't know. In the latter case, the neutrino is its own antiparticle, and neutrinoless double beta decay is possible, and is being sought for experimentally. -- Gene From: Bill Gosper <billgosper@gmail.com> To: math-fun@mailman.xmission.com Sent: Tuesday, July 28, 2015 4:32 PM Subject: Re: [math-fun] nuclide map Another selenium oddity: Both Se74 and Se82 are stable (and uncommon), but are unstable under the addition or removal of a proton, neutron, or both, or swap.

Somewhat off-topic I know, but observation of neutrinoless double beta decay would apparently decide a question which has long intrigued me: is there any fundamental physical procedure for discriminating between relativistic physicists' x^2 + y^2 + z^2 - t^2 and particle physicists' t^2 - x^2 - y^2 - z^2 ? A long paper http://arxiv.org/abs/math-ph/0012006 much of which goes over my head --- and is further obscured by a crucial misprint on page 50, where "Pin(1,3)" should read "Pin(3,1)" --- claims that a positive result would support the former convention (much to my personal satisfaction). Sadly, more recent experimental estimates of the lifetime have grown unfeasibly large --- see eg. http://arxiv.org/pdf/1402.1170.pdf passim ...
