Helium discovery
Each atom of helium-4 is a boson particle, by virtue of its integer spin. A helium-3 atom is a fermion particle; it can form bosons only by pairing with another particle like itself at much lower temperatures. The discovery of superfluidity in helium-3 was the basis for the award of the 1996 Nobel Prize in Physics.Helium hydride is actually a molecular cation, HeH +. In 1925, chemists Thorfin R. Hogness and E. G. Lunn at the University of California, Berkeley, bombarded a hydrogen–helium mixture at low pressure and observed the presence of HeH + and possibly HeH 2+. Not much was thought of this discovery until the 1970s, when astronomers conjectured ...

Mar 29, 2020 · He named the element helium, from the Greek word helios, meaning sun. While historians credit Janssen and Lockyer with the discovery of helium, Sir William Ramsay, a Scottish chemist, as well as two Swedish chemists who worked independently of Ramsay, Nils Langlet and Per Theodor Cleve, were the first to isolate it in the lab.

On that day, back in 1868, French astrophysicist Pierre Janssen became the first person to.The discovery of the CMB in the mid-1960s curtailed interest in alternatives such as the steady state theory. [51] In the late 1940s Alpher and Herman reasoned that if there was a Big Bang, the expansion of the universe would have stretched the high-energy radiation of the very early universe into the microwave region of the electromagnetic spectrum , and …
Scientific discoveries The first evidence of helium was observed on August 18, 1868, as a bright yellow line with a wavelength of 587.49 nanometers in the spectrum of the chromosphere of the Sun. The line was detected by French astronomer Jules Janssen during a total solar eclipse in Guntur, India. Mar 26, 2019 · Lockyer called the new element helium, after the Greek word for sun. Both Janssen’s and Lockyer’s papers describing their observations landed at the French Academy of Sciences on the same day, and both men received credit for the discovery of the “new” element.
