Indium (49 In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide (115 In) being measurably though weakly radioactive. Its spin-forbidden decay has a half-life of 4.41×10 14 years, much longer than the currently accepted age of the Universe. The stable isotope 113 In is only 4.3% of
Conversely, of the 251 known stable nuclides, only five have both an odd number of protons and odd number of neutrons: hydrogen-2 , lithium-6, boron-10, nitrogen-14, and tantalum-180m. Also, only four naturally occurring, radioactive odd–odd nuclides have a half-life >10 9 years: potassium-40 , vanadium-50 , lanthanum-138 , and lutetium-176 .
Indium has 39 known isotopes, ranging in mass number from 97 to 135. Only two isotopes occur naturally as primordial nuclides: indium-113, the only stable isotope, and indium-115, which has a half-life of 4.41 × 10 14 years, four orders of magnitude greater than the age of the Universe and nearly 30,000 times greater than half life of thorium ...

LeShuttle has a fleet of 15 HGV shuttle trains which each have a locomotive on each end, 31 or 32 mostly open vehicle-carrying wagons (train cars), three loading/unloading wagons (one on either side of the train and one in the middle), and a single passenger carriage called the "club car" which is 25.72 m (84 ft 5 in) long.
The aim of this experiment had been to synthesise the isotopes 281 113 and 282 113 that would fill in the gap between isotopes produced via hot fusion (283 113 and 284 113) and cold fusion (278 113). After five alpha decays, these nuclides would reach known isotopes of lawrencium , assuming that the decay chains were not terminated prematurely ...

Re-narrated Horizon episode, first aired in the UK in 1972. [4]We give you a behind-the-scenes look at the making of a nature film. Oxford Scientific Films Unit shows how it tackles such problems as filming a wood wasp laying its eggs inside trees, the hatching of a chick and the courtship rituals of the stickleback.
