Student Research appearing at National Physics Meetings

Research work done by a number of current and former Augustana College students will be presented at two national meetings this spring. Junior Russ Averin, of Sioux Falls, will speak at the April Meeting of the American Physical Society (APS) in Denver. This meeting is hosted by six of the 14 divisions of APS annually, including the Divisions of Particles and Fields, Astrophysics, and Nuclear Physics. Averin will speak on May 2 nd in the session devoted to WZ physics. His talk, a report on collaborative work done with Assistant Professor Drew Alton, is entitled “Search for a scalar or vector particle decaying into Z g in proton-antiproton collisions at = 1.96 TeV”. The talk is a follow-up to their recent publication in Physics Letters B and is part of the analysis of the experiment at the Fermi National Accelerator Laboratory. This work was partially supported by the Augustana Research and Artists Fund.

Later that month, work completed by sophomore Bethany Jochim of Pierre and former students Amy Lueking (’07, Sioux Falls) and Laura Doshier (’07, Rapid City) will form the basis of an invited talk at the APS Division of Atomic, Molecular, and Optical Physics (DAMOP) meeting in Charlottesville, Virginia. The talk will be given during the May 21 st focus session on collision-induced states in molecules by Augustana faculty member Eric Wells. Jochim and co-workers investigated bond rearrangement leading to formation of H 3 + following the ionization of ammonia and methane. Support for this research, done in collaboration with Eli Parke, Mat Leonard, Kevin Carnes, and Itzik Ben-Itzhak of the J.R. Macdonald Laboratory at Kansas State University was obtained from Research Corporation, National Science Foundation award PHY-0653598, and the Chemical Sciences, Geosciences, and Biosciences Division, Office of Basic Energy Sciences, US Department of Energy.

Also at the DAMOP meeting, work done by Augustana students Michael Todt (junior from Moorhead, MN), Nick Smolnisky (senior from Sioux Falls), Nate Jastram (senior from Sioux Falls), and Bethany Jochim (sophomore from Pierre), along with mentor Eric Wells, will be presented in a contributed session. This work, entitled “Enhancing the feedback signals used in closed-loop control of molecular fragmentation”, explores methods of improving laser control of molecular dissociation. The experiments were again done in collaboration with members of the Kansas State group, including Augustana alumna Nora G. Johnson (’05, Dell Rapids), Jarlath Mckenna, Max Sayler, Bishwanath Gaire, Mohammed Zohrabi, Kevin Carnes, and Itzik Ben-Itzhak. The work was supported by National Science Foundation award PHY-0653598, and the Chemical Sciences, Geosciences, and Biosciences Division, Office of Basic Energy Sciences, US Department of Energy.
