• #### Jim Lawler's Science: Above and Below the H-Line ﻿

(2018-04-27)
This presentation gives an overview of Jim Lawler's career, focusing on a few of his important contributions to science.
• #### JimFest Overview ﻿

(2018-04-27)
Overview of the 2018 Wisconsin Atomic Spectroscopy Seminar in honor of Prof. James E. Lawler. Includes biographical information and the scientific program.
• #### Measurements of branching fractions using Fourier transform and grating spectroscopy ﻿

(2018-04-30)
The measurement of lifetimes using laser-induced fluorescence at the University of Wisconsin-Madison has been one of the most productive experiments in the measurement of atomic spectroscopic data. The NIST bibliographic ...
• #### Non-Degenerate Four-Wave Mixing through Rydberg States in a MOT ﻿

(2007-07-02)
In this work, we use a three-photon near-resonant process in a laser-cooled Rb vapor to achieve phase-matched four-wave mixing using an intermediate Rydberg state. Rydberg atoms in the 36D5/2 state are efficiently produced ...
• #### Physics Challenges for Spin-Exchange Optical Pumping of He-3 ﻿

(2009-05-28)
Presentation given at the "Physics and Applications of Polarized Noble Gases" workshop at the University of Virginia, May 19, 2009.
• #### A Portable SERF Magnetometer for Biomagnetic Measurements ﻿

(2009-09-10)
Recent developments on the UW SERF magnetometer.
• #### A Portable Ultrasensitive SERF Atomic Magnetometer for Biomagnetic Measurements ﻿

(2007-07-02)
We present a portable Rb cell atomic magnetometer suited for biomagnetic measurements. Working in the spin-exchange relaxation free regime, we demonstrate an initial white noise floor of 60 fT/sqrt {Hz}. We show an adult ...

• #### RayTrace ﻿

(1998-03-13)
This applet traces paraxial light rays through a user-specified system of up to 12 ideal thin lenses and apertures, allowing many simple optical instruments to be modelled. Three examples are given: coupling of light from ...
• #### Six Lines to Tell a Story ﻿

(2018-04-27)
In this talk, I will highlight a recently completed investigation into a challenge brought against our earlier work on vanadium. The discrepancy between six transition probabilities and its resolution touches on several ...
• #### Small Angle X-ray Scattering from Protein Solutions ﻿

(1954-01-14)
• #### Spectroscopic study of the 7p J=1/2 and 7p J=3/2 states in neutral cesium-133 ﻿

(2018-04-27)
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. ...
• #### Transition Probabilities for Neutral Cerium from Boltzmann Analysis of Fourier Transform Spectra ﻿

(2018-04-27)
Poster presentation on Cerium transition probabilities
• #### Ultrasensitive Atomic Magnetometers ﻿

(2009-09-10)
We have developed a novel, small-volume portable single-channel atomic biomagnetometer and have used it to detect adult MCG signals. The cryogenic-free magnetometer has sufficiently high sensitivity (20 fT/rt(Hz)) that ...
• #### UW Laboratory Astrophysics ﻿

(2018-04-27)
In this talk I will describe the laboratory astrophysics program of the Jim Lawler group at the University of Wisconsin – Madison, focusing on the laboratory techniques and instruments used for the measurement of transition ...
