[8] However, in 1912 the Finnish mathematician Karl Fritiof Sundman proved that there exists an analytic solution to the three-body problem in the form of a Puiseux series, specifically a power series in terms of powers of t 1/3. [9] This series converges for all real t, except for initial conditions corresponding to zero angular momentum.
Tin-121m (121m Sn) is a radioisotope and nuclear isomer of tin with a half-life of 43.9 years. In a normal thermal reactor, it has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste. Fast fission or fission of some heavier actinides will produce tin-121 at higher yields. For example, its yield ...
Tris(8-hydroxyquinolinato)aluminium is the chemical compound with the formula Al(C 9 H 6 NO) 3. Widely abbreviated Alq 3 , it is a coordination complex wherein aluminium is bonded in a bidentate manner to the conjugate base of three 8-hydroxyquinoline ligands .
Members of President-elect Donald Trump's transition team are drawing up a list of military officers to be fired, potentially to include the Joint Chiefs of Staff, two sources said, in what would ...
Niobium–tin is an intermetallic compound of niobium (Nb) and tin (Sn), used industrially as a type-II superconductor. This intermetallic compound has a simple structure: A3B . It is more expensive than niobium–titanium (NbTi), but remains superconducting up to a magnetic flux density of 30 teslas [T] (300,000 G), [ 1 ] compared to a limit ...
