Date/Time: Thu 2004-04-15 at 15:00

Location:  Auditorium          

Speaker:   Khashayer Ghandi and W.A. MacFarlane (Chemistry Department, UBC)

Title:     Flemfest: In celebration of Don Fleming's Glen Seaborg award.

Abstract: Muonium Chemistry, Yesterday, Today and Tomorrow: Khashayar Ghandi

Professor Don Fleming initiated Muonium chemistry almost thirty years ago and since then has done extensive research in this field. I will present a few of his studies and his major accomplishments. Then I will give examples where Muonium chemistry has some underdeveloped and unexplored areas and how we are trying to discern a few of these unknowns. I will also present some future directions for Muonium chemistry.

Beta-NMR: A Nulear Probe for Nanoscience: W.A. MacFarlane

Like muon spin rotation, beta-detected NMR measures magnetic resonance and relaxation phenomena using a radioactive probe. By virtue of the easy detectability of the high energy decay products of nuclear disintegrations, radioactive nuclei have found many applications in chemistry and condensed matter physics particularly in situations where conventional methods are hampered by the relative scarcity of the atoms of interest, for example condensed systems of nanoscopic dimension. I will describe the TRIUMF/ISAC implementation of beta-NMR, comparing it to muon spin rotation, and end with some speculation about possible apllications in chemistry.

Reception to follow in TRIUMF courtyard/cafeteria.
