Presentation Transcript

  1. Nuclear Chemistry@Indiana Vic Viola Summer 2005 (http://nuchem.iucf.indiana.edu)

  2. Vic as a prolific scientist • authored 175 journal publications • 82 conference proceedings • numerous talks at seminars, conferences, and workshops • served as PhD advisor for 18 graduate students • mentored 15 postdoctoral fellows • Three undergrads won Undergraduate ACS award in Nuclear Chemistry (see symposium brochure for details)

  3. Despite his cosmopolitan outlook, Vic is without question a Midwesterner – after all he was born in Abilene, Kansas He received an A.B in 1957 from the University of Kansas (but did you know he started out as an English major?) He was awarded his Ph.D. in 1961 from the University of California, Berkeley (where he was active on many fronts…) Viola, V.E. Angular distributions from heavy-ion-induced fission. Ph.D. Thesis, University of California, Berkeley, 1961.

  4. Where does Vic do all that writing (including “Letters to the editor”) ?

  5. Vic and Nancy, relaxing in their backyard

  6. Always an experimentalist at heart The equipment seems to change but Vic doesn’t…

  7. Vic is the quintessential interdisciplinary scientist “Historically, chemists have played an active role in the study of nuclear interactions between complex nuclei. […]” As a chemist, Vic has concerned himself not only with the reactions nuclei undergo (fission, damped reactions) but with their possible phase transition from a liquid to a gas.

  8. # of atoms Time (years) The way Vic looks 1986 2000 2004

  9. # of atoms Time (years) The way Vic looks 2004 From the slope of this line we can predict Vic will be doing well 20 years from now – but how about the other direction ?

  10. Vic is always blazing new trails. Here he is on the Appalachian Trail in 1978

  11. About to go out on a protest- the Berkeley days.

  12. Vic, we always knew you were a soldier at heart!

  13. Vic and sports

  14. Erin Renshaw Vic’s nuclear family Microsoft (students, postdocs, and collaborators) These are the students who built ISiS? Kevin Morley, LANL Dave Bracken, LANL

  15. Vic’s “other” family

  16. Vic’s “other” family Charley, Randy, and Gina trust that Dad will figure out how to operate this complex device.

  17. The ISiS adventure Reproducing the condition of high temperature on earth

  18. Bringing Stars Down to Earth Victor Viola, Distinguished Professor of Chemistry, and Kris Kwiatowski, Senior Scientist in Chemistry, both at Indiana University Bloomington, and Lai Wan Woo (right to left), who served as a computer consultant in the design of the Indiana Silicon Sphere detector array (ISiS), are in front of the central control panels at the Indiana University Cyclotron Facility. In the foreground, the monitor screen shows a line drawing of the ISiS detector assembly. Indiana University, Research & Creative Activity April 1998 Volume XXI Number 2 Left to right: Gary Fleener, John Dorsett, Kenny Bastin “…thermo physics of nuclei as mesoscopic clusters and of the process of liquid-vapor phase transition...”– I.Y. Lee

  19. Nothing but the finest as ISiS goes to Saclay for its first experiment Kris Kwiatkowski at SATURNE

  20. ISiS goes to Brookhaven National Lab (AGS)

  21. Themes in Vic’s research Nucleosynthesis 1960 1970 1980 1990 2000 Fission Damped Reactions Non-equilibrium light particle emission Multifragmentation and the nuclear liquid-gas phase transition

  22. Liquid-gas Phase transition? Probability for emitting one or more IMF exceeds probability for emitting none. Several quantities tell us that something unusual happens at E*/A=4-6 MeV for a Au nucleus Charge distribution (Z) becomes flat. Onset of an expansion L. Beaulieu et al., PRL 84 5971 (2000) IMF Emission time becomes very short

  23. … and the irony is … After 40 years we are returning to study fission, specifically the fission of N/Z exotic nuclei K.-H. Schmidt, J. Benlliure, and A.R. Junghans Nucl. Phys. A693, 169 (2001) Moller, Madland, Sierk, and Iwamoto Nature 409, (2001) 785-790.

  24. Fission in the Era of Radioactive Beams

  25. December 2000, Vic is the recipient of the 2000 Tracy M. Sonneborn Award Courtesy of Indiana University http://broadcast.iu.edu/lectures/sonneborn “I recognized a long time ago that if you can define a problem for students, give them the resources to work on that problem, you get remarkable results…” – Vic Viola, Tracy M. Sonneborn lecture Dec. 2000

  26. Thanks Vic! (from all the past and present members of the Nuclear Chemistry group at Indiana)
