JIMFEST 2018
Spectroscopic study of the 7p J=1/2 and 7p J=3/2 states in neutral cesium-133
Date: Friday, April 20th
Time: 2:00 pm
Place: 2241 Chamberlin Hall
Speaker: Maria-Teresa Herd, Mt. Holyoke College
Abstract: I will start with a few observations of connections between spectroscopy and other (seemingly unrelated) research topics, then focus on Doppler free spectroscopy on the 7p J=1/2 and 7p J=3/2 states in neutral cesium-133. A frequency doubled titanium sapphire laser stabilized to a temperature stabilized ultra-low expansion optical cavity was used to find the absolute frequencies for the centers of gravity of the two cesium states. These measurements are an improvement of a factor of 650 and 500 over previously reported measurements. The magnetic dipole and electric quadrupole constants were also measured and found to be consistent with previously published values.
