Article Synopsis
- Negative ions play a crucial role in various scientific fields such as interstellar chemistry and anti-matter research, where their unique properties are influenced by electron-correlation effects.
- Traditional methods for studying these ions face challenges due to their loosely bound nature and limited optical transitions, hindering high-resolution detection techniques.
- A new method has been developed that accurately measures negative ion binding energies with significantly higher precision, utilizing laser manipulation and a cryogenic ion-beam storage ring, leading to a reported electron affinity of 1.461 112 972(87) eV for oxygen.
We use a novel electrostatic ion storage ring to measure the radiative lifetime of the upper level in the 3p^{5} ^{2}P_{1/2}^{o}→3p^{5} ^{2}P_{3/2}^{o} spontaneous radiative decay in ^{32}S^{-} to be 503±54 sec. This is by orders of magnitude the longest lifetime ever measured in a negatively charged ion. Cryogenic cooling of the storage ring gives a residual-gas pressure of a few times 10^{-14} mbar at 13 K and storage of 10 keV sulfur anions for more than an hour.

Material And Methods: One hundred and nine articles published between 2002 and 2008 were analysed. Bibliometric methods used were as follows: information on peer review, impact factor (IF), the Science Citation Index (SCI) and the representation of Norwegians in the list of authors.
Objective: In Norway, very little data are available on the relation between the total number of research projects on the clinical development of drugs that have been started, the number of these projects in which the research phase has been completed and the number of projects for which results have been published. The aim of this study was to determine the number of projects in which the research phase had been completed and the results published.
Material And Methods: Information on research projects carried out on the clinical development of drugs during the year 2000 was obtained from the archives of the Norwegian Research Ethical Committee (REC) and subsequently analysed.
Objective: Little has been published either concerning the total number of research projects in connection with clinical development of drugs or the number of projects financially supported by the industry.
Methods: From the archives of the five regional Norwegian Research Ethical Committees (REC), all research projects in connection with clinical development of drugs for the years 2000 and 2004 were analysed with the intention of finding the number of projects financially supported by the industry, the type of research institution, the industrial company, the topic of the research as classified in the international Anatomic Therapeutic Classification system (ATC), the research phase and the approval status of the drug by the Norwegian Medicines Agency (NMA).
Results: The total number of research projects for the clinical development of drugs for the years 2000 and 2004 was 489, and 75.
