Atom-at-a-time laser resonance ionization spectroscopy of nobelium

Atom-at-a-time laser resonance ionization spectroscopy of nobelium | Nuclear Physics | Scoop.it
Optical spectroscopy of a primordial isotope has traditionally formed the basis for understanding the atomic structure of an element. Such studies have been conducted for most elements and theoretical modelling can be performed to high precision, taking into account relativistic effects that scale approximately as the square of the atomic number. However, for the transfermium elements (those with atomic numbers greater than 100), the atomic structure is experimentally unknown. These radioactive elements are produced in nuclear fusion reactions at rates of only a few atoms per second at most and must be studied immediately following their production, which has so far precluded their optical spectroscopy. Here we report laser resonance ionization spectroscopy of nobelium (No; atomic number 102) in single-atom-at-a-time quantities, in which we identify the ground-state transition 1S0 nature19345-m17gif1K3323 1P1. By combining this result with data from an observed Rydberg series, we obtain an upper limit for the ionization potential of nobelium. These accurate results from direct laser excitations of outer-shell electrons cannot be achieved using state-of-the-art relativistic many-body calculations that include quantum electrodynamic effects, owing to large uncertainties in the modelled transition energies of the complex systems under consideration. Our work opens the door to high-precision measurements of various atomic and nuclear properties of elements heavier than nobelium, and motivates future theoretical work.

Antiproton charge radius | Nuclear Physics | Scoop.it
Taking advantage of the new Extra Low ENergy Antiprotons (ELENA) ring and anti-proton decelerating facility at CERN, the authors propose to measure the Lamb shift of anti-hydrogen. This equates to a measurement of the anti-proton radius for the first time at the 10% level as well as a test of the fundamental CPT symmetry.

For the first time scientists have measured the radius of a calcium nucleus with 32 neutrons – indicating that nuclear physics theories don’t describe atomic nuclei as well as previously thought. The study, conducted by CERN scientists at the ISOLDE facility and published in the latest issue of the journal Nature Physics, aimed to understand whether calcium has more than two magic numbers.

Molybdenum-99 for Medical Imaging

Molybdenum-99 for Medical Imaging | Nuclear Physics | Scoop.it
Download a PDF of "Molybdenum-99 for Medical Imaging" by the National Academies of Sciences, Engineering, and Medicine for free. Description: The decay product of the medical isotope molybdenum-99 (Mo-99), technetium-99m (Tc-99m), and associated medical isotopes iodine-131 (I-131) and xenon-133 (Xe-133) are used worldwide for medical diagnostic imaging or therapy. The United States consumes about half of the world’s supply of Mo-99, but there has been no domestic (i.e., U.S.-based) production of this isotope since the late 1980s. The United States imports Mo-99 for domestic use from Australia, Canada, Europe, and South Africa.

Mo-99 and Tc-99m cannot be stockpiled for use because of their short half-lives. Consequently, they must be routinely produced and delivered to medical imaging centers. Almost all Mo-99 for medical use is produced by irradiating highly enriched uranium (HEU) targets in research reactors, several of which are over 50 years old and are approaching the end of their operating lives. Unanticipated and extended shutdowns of some of these old reactors have resulted in severe Mo-99 supply shortages in the United States and other countries. Some of these shortages have disrupted the delivery of medical care. Molybdenum-99 for Medical Imaging examines the production and utilization of Mo-99 and associated medical isotopes, and provides recommendations for medical use.
