Exploring an 'island of inversion,' physicists find new clues to element synthesis in supernovaeElements heavier than iron come into being only in powerful stellar explosions, supernovae. During nuclear reactions all kinds of short-lived atomic nuclei are formed, including more stable combinations "“ the so-called magic numbers "“ predicted by theory. Yet here, too, there are exceptions: the islands of inversion. Headed by physicists from the Excellence Cluster Universe at the...

Researchers at the Department of Energy's Oak Ridge National Laboratory (ORNL), the University of Tennessee (UT) and six collaborating universities have performed an unprecedented nuclear reaction experiment that explores the unique properties of the "doubly magic" radioactive isotope of 132Sn, or tin-132. The research, published in the journal Nature, is part of a broad scientific effort to understand nucleosynthesis, or the process by which the higher elements (those in the periodic table...

A giant laser -- the size of three football fields -- is being used by scientists at a government lab in California to possibly set off a nuclear reaction so intense that it will make a star bloom on the surface of the Earth, according to a recent CNN report. The scientists at the Lawrence Livermore National Laboratory want to create a sun on the ground that seems like a science fiction fantasy straight from Hollywood. But the experiment is for real, and the National Ignition Facility will...

Experiments by British scientists could reveal the make-up of the universe, the University of Liverpool said Thursday. The examinations will become part of the Advanced Gamma Tracking Array experiment, which seeks to create a so-called fingerprint of the inside of the atomic nucleus to help scientists understand the universe's structure, including humans and stars, the university said in a release. Scientists will analyze particle interactions that produce gamma rays, the university said, and...

A U.S. Navy laboratory has produced "significant" evidence of the controversial energy source known as cold fusion, the Associated Press reported. Researchers are calling it the first clear visual evidence that low-energy nuclear reaction (LENR), or cold fusion devices can produce neutrons capable of nuclear reactions. Analytical chemist Pamela Mosier-Boss of the U.S. Navy's Space and Naval Warfare Systems Center (SPAWAR) in San Diego, California, called the finding "very significant."...

New evidence for existence of controversial energy source Researchers are reporting compelling new scientific evidence for the existence of low-energy nuclear reactions (LENR), the process once called "cold fusion" that may promise a new source of energy. One group of scientists, for instance, describes what it terms the first clear visual evidence that LENR devices can produce neutrons, subatomic particles that scientists view as tell-tale signs that nuclear reactions are occurring....

NIST -- A key process that enhances the production of nuclear energy in the interior of dense stars has been re-created in the laboratory for the first time by physicists at the National Institute of Standards and Technology (NIST). The work may help scientists study topics such as nuclear fusion as a possible energy source and demonstrates a new method for studying and modeling dense stellar objects such as white dwarfs. The NIST experiments, described in the Jan. 18 issue of Physical...
