A team of researchers from the RIKEN Nishina Center for Accelerator-Based Science in Japan has demonstrated that the magic numbers 20 and 28 disappear from all neutron-rich magnesium isotopes, thereby establishing a new, larger area of nuclear deformation in the nuclear chart. The Japanese study, published today in the prestigious journal Physical Review Letters, was made possible by the intense beam at the Radioactive Beam Factory (RIBF) at RIKEN, which produces the most intense...

Key experiment in nuclear physics Stable tin, as we know it, comprises 112 nuclear particles — 50 protons and 632 neutrons. The neutrons act as a kind of buffer between the electrically repelling protons and prevent normal tin from decaying. According to the shell model of nuclear physics, 50 is a "magic number" that gives rise to special properties. Tin-100, with 50 protons and 50 neutrons, is "doubly magic," making it particularly interesting for nuclear physicists. Shooting...

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...

Moving Closer to Understanding the Island of Stability A team of scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory has detected six isotopes, never seen before, of the superheavy elements 104 through 114. Starting with the creation of a new isotope of the yet-to-be-named element 114, the researchers observed successive emissions of alpha particles that yielded new isotopes of copernicium (element 112), darmstadtium (element 110), hassium (element 108),...

Tin may seem like the most unassuming of elements, but experiments performed at the Department of Energy's Oak Ridge National Laboratory are yielding surprising properties in extremely short-lived isotopes near tin-100's "doubly magic" nucleus. Experiments performed with the exotic nucleus tin-101, which has a single neutron orbiting tin-100's closed shell of 50 protons and 50 neutrons, indicate an unexpected reversal in the ordering of lowest states in the nucleus. The finding appears to...

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...

OPEC Secretary General Abdalla Salem El-Badri told world leaders in Switzerland that oil priced at $50 a barrel would not fund new oil field development. I hope the price will pick up "¦ a $50 price will not permit us to invest, he said at the World Economic Forum in Davos, Switzerland, Thursday, The Times of London reported. Members of the Organization of Petroleum Exporting Countries are not happy with $40, even $50 a barrel, he said. He said OPEC members will not hesitate to take...

With help from newly developed equipment designed and built at Michigan State University, MSU researchers have been able to make first-of-its-kind measurements of several rare nuclei, one of which has been termed a "holy grail" of experimental nuclear physics. The discoveries, made at MSU's National Superconducting Cyclotron Laboratory using an isotope purification device, will help to refine theoretical models about how elements are created in the cosmos. Until now, this was beyond the...
