The 1971 discovery that helium-3 becomes a superfluid at a temperature of 0.0027 K has garnered David M. Lee, Douglas D. Osheroff, and Robert C. Richardson the 1996 Nobel Prize in Physics. Lee and Richardson are physics professors at Cornell University. Osheroff, a Cornell graduate student at the time of the discovery, is now a …
Helium-3 was originally thought to be a radioactive isotope until it was found in samples of natural helium,, taken both from the terrestrial atmosphere and from natural gas wells. Other than 1H, helium-3 is the only stable isotope of any element with more protons than neutrons. Its presence is rare on Earth, it is sought after for use in ...

Helium-3 is an isotope, or version, of helium that has only one neutron instead of two. It is considered to be a promising fuel for nuclear fusion reactions, a speculative energy source based on ...
Helium-3 mining on the lunar surface. The idea of harvesting a clean and efficient form of energy from the Moon has stimulated science fiction and fact in recent decades. Unlike Earth, which is protected by its magnetic field, the Moon has been bombarded with large quantities of Helium-3 by the solar wind. It is thought that this isotope could ...
The Superfluid Phases Of Helium 3. D. Vollhardt, P. Wölfle, R. Hallock. Published 1 July 1990. Physics. A comprehensive treatment of the theory of superfluid helium-3 is presented in this book. This treatment also illustrates many of the principal themes of theoretical condensed matter physics over the past two decades.
Helium-3 was a constituent of the dust and gases that coalesced approximately 4.5 billion years ago. And because of its nature, it became locked into the core. But some process has been...
The Helium-3 isotope has a wide range of applications, helping to save lives, advance high-tech industries, and expand scientific frontiers. Applications include: Quantum Computing and Cryogenics. He-3 is used in quantum computing and modern cryogenics research to achieve extremely low temperatures (as low as a few millikelvin). …

Scientists say two fully-loaded Space Shuttle cargo bay's worth of Helium-3 — about 40 tonnes worth of the gas — could power the United States for a year at the current rate of energy consumption. Professor Ouyang Ziyuan, the chief scientist of the Chinese Lunar Exploration Program, recently said, the moon is "so rich" in Helium-3 ...
In contrast, helium-3 is a completely clean source of energy. Two helium-3 atoms are fused in a thermonuclear reactor to produce normal helium and energy. The fuel is non-radioactive, the process produces no radioactivity, and the residue produces no radioactivity. It is the perfect energy source. However the helium-3 reaction takes place …
Helium-3 filled proportional counter RS-P4-0203-201 Neutron time-of-flight spectroscopy and small-angle scattering measurements Versatile detector This proportional counter is a versatile detector in a small envelope – ideal for applications requiring excellent angular resolution. With its high sensitivity, temperature
While helium-3 is scarce on Earth, it is surprisingly abundant on the Moon, where it has been deposited over billions of years by the solar wind. Helium-3 and Nuclear Fusion. The true promise of helium-3 lies in its potential application within nuclear fusion reactors. Unlike conventional nuclear fission, which divides heavy atoms like uranium ...
The Department of Energy Isotope Program Fills Critical Government Needs for Helium-3. An Earlier Shortage Has Been Mitigated. The Department of Energy (DOE) has supplied isotopes and isotope-related services principally to the Nation, but also globally, for more than 50 years. DOE projects its helium-3 (3He) recovery and inventory management …
3. On the basis of the Big Bang theory scientists predicted levels of Helium-3 in the universe that are ten times greater than the levels actually observed . According to the original model, Helium-3 is produced when low-mass stars burn up hydrogen and become 'red giants', as well as being produced in the Big Bang itself.
In 1986, scientists at the Institute of Fusion Technology at the University of Wisconsin estimated that the lunar "soil", called the regolith, contains one million tons of helium-3 ( 3 He), a material that could be …
Helium-3 is an isotope, or variant, of helium that has one neutron instead of the usual two in its nucleus. It's a rare gas, making up just 0.0001% of helium on Earth. It comes from various ...

In the preface to Helium Three, E. R. Dobbs says that his aim was "to provide a book, in the spirit of [John] Wilks' monograph, covering all known properties of 3 He at low temperatures." In this Dobbs has succeeded in superb fashion. In the book's foreword, Olli Lounasmaa, author of Experimental Principles and Methods below 1K (Academic Press, …
A party balloon filled with helium deflates to 3 2 of its original volume in 8.0 hours. How long will it take an identical balloon filled with the same number of moles of air (M = 28.2 g / mol) to deflate to 2 1 of its original volume?
This helium-3 could potentially be extracted by heating the lunar dust to around 600 degrees C, before bringing it back to the Earth to fuel a new generation of nuclear fusion power plants. As reported in an Artemis Project paper, about 25 tonnes of helium-3 -- or a fully-loaded Space Shuttle cargo bay's worth -- could power the United …

Helium-3 in Milky Way Reveals Abundance of Matter in Early Universe. Astronomers using the National Science Foundation's 140 Foot Radio Telescope in Green Bank, West ia, were able to infer the amount of matter created by the Big Bang, and confirmed that it accounts for only a small portion of the effects of gravity observed in the …
Helium-3 is an isotope of helium, which means it contains the same number of protons as this common element but a different number of neutrons. This isotope is considered a potentially...
Expert-verified. Incorrect Question 3 0/1 pts The n = 3 standing wave is set up in a tube that is open at both ends in normal air. Then the tube is moved to an enclosed box filled with helium, where the speed of sound is 3x larger than the speed of sound in air. What standing wave harmonic (n) in helium will have the same frequency as the ...
The trace of the isotope helium-3 on Earth is attributable to the negative beta decay of the rare hydrogen-3 isotope . Helium-4 is by far the most plentiful of the stable isotopes: helium-4 atoms outnumber those of helium-3 about 700,000:1 in atmospheric helium and about 7,000,000:1 in certain helium-bearing minerals.
