Ort: Seminarraum Blaum
Redner: Prof. Albert Viggiano, Plasma Chemistry Laboratory, Albuquerque New Mexico
Titel: Recent Studies in Plasma Chemistry


This talk will give an overview of recent work at the Plasma Chemistry Laboratory in Albuquerque New Mexico. The talk will start with chemistry relating to ionospheric medication involving chemi-ionization of lanthanide metals. I will then discuss a variety of metal ion reactions related to catalysis and the detailed mechanistic understanding that statistical modeling of temperature dependences can yield. Finally, results from a quantifiable technique to measure ion radical reactions will be shown.

Titel: Progress of mass measurements of short-lived nuclides at the heavy-ion storage ring in Lanzhou


Recent commissioning of the Cooler Storage Ring at the Heavy Ion Research Facility in Lanzhou enabled us to conduct high-precision nuclear mass measurements at the Institute of Modern Physics in Lanzhou (IMP). In the past few years, mass measurements were performed using the storage-ring-based isochronous mass spectrometry (IMS) via the fragmentation of the energetic 36Ar, 40Ar, 58Ni, 78Kr, 86Kr, and 112Sn projectiles. Masses of short-lived nuclides on both sides of the β-stability line have been measured. Relative mass precisions of 10-6 ~10-7 are routinely achieved and some issues in the studies of nuclear structure and nuclear astrophysics have been addressed [1-6]. In this seminar, the technique details and experimental results are presented, and recent progress and some preliminary results are briefly introduced. The IMS with double ToF detectors for velocity measurements are also developed in CSRe, the future experiments using this double ToF IMS are discussed.
