"Ionization Phenomena in Ion-Atom Collisions"
Assistant Professor of Physics, Bridgewater State College 1999
I like to say that I smash atoms, and I do, but it is not entirely for the fun of it. I investigate atomic and molecular structure and electronic interactions (excitation, ionization, capture...) using collisions, smashing atoms. This means I explore the ways in which bound and free electrons configure or develop about atoms and molecules (including the continuum) in response to interactions initiated by a collision or some external field. The knowledge of collisions and how electrons behave themselves during collisions is integral in understanding parts of the universe made from atoms, ions and molecules-from chemical reactions here on earth to the spectroscopy of planetary atmospheres and astrophysical plasmas. On campus I have a high resolution electron and ion spectrometer to measure elastic and inelastic scattered electrons, Auger electrons, and recoil ions - all of which yield detailed information on the collision interactions and the electronic structure and dynamics. Toward the end of the spring semester 1998 my student, Rudy Magyar, and I successfully constructed the entire apparatus and then smashed electrons into gaseous single-atomic targets. Here are some of our preliminary results and a look at the spectrometer. In the future I hope to look at collisions using solid targets and laser excited atomic targets. I am interested in many other problems in physics including one that I took part in while I was a post-doc as Oak Ridge National Laboratory where, at CERN ,we produced electron-positron pairs by the transient Coulomb fields created by lead ions (traveling at 0.99996 times the speed of light) interacting with fixed targets. This semester I will be working with two former students on several Chaos demonstrations and the analytical description of the results. In general, I get a genuine kick out of teaching and rethinking physics every day. I also like to play basketball and tennis with students and with whomever else I can find. I have a NTRP rating of 4.5 - 5.0 in tennis.

Construction of a 780 nm Tunable Diode Laser I got the dough so I am ready to go! Starting in the Fall of 2000. Please check out this link for more details and e-mail me to let me know if you are interested in working with me on this project that will lead to Doppler and Doppler-free Saturated Absorption Spectroscopy for starters and atom cooling and trapping to be developed.
