OPTI 474/574 Atomic Physics for Experimentalists (3) II. (Identical with Phys.474/574.) Experimental techniques to generate, analyze and detect photons from X-ray to IR; interpretation of spectra from gases, liquids, solids and biological macromolecules; light scattering, polarization.

Course Outline (75-minute lectures):

This course is for the experimentalist and the theorist. Like OPTI 473/573, it deals with the experimental techniques needed to check results predicted by Atomic Theory. It will cover both new topics and some selected topics from 473/573 in more detail. Topics will be selected from the following list. Topics 1, 2 and 3 will comprise the first part of the course.

1. Interferometry - Fabry Perot and Michelson Interferometers, Fourier Spectroscopy, high resolution spectroscopy, the shift and shape of
spectral lines, convolutions.

2. Atomic Spectra - X-rays, complex spectra, many electron spectra, molecular spectra autoionization and Auger electron spectroscopy, molecular orbit theory and X-ray lasers.

3. Applications - Energy levels, mean lives, transition probabilities, line intensities, particle densities, plasma diagnostics, temperature measurements, electric and magnetic field measurements.

4. Spectroscopic Techniques - Beam foil, phase shift, Hanle effect, level crossing, relative and absolute intensity calibrations.

5. Spectroscopic Sources - Beam-foil, hollow cathode, pulsed electron, q - pinch, sliding spark, laser induced plasma, high frequency discharge.

6. Instruments – Photographic films and plates, photomultipliers, photodiodes, CCD’s and other detectors, gratings (ruled and holographic), optical multichannel analyzers, solid state detectors, optical interfacing – lenses, mirrors, optical fibers, computer interfacing – detector to NIST-NBS standards.

7. Spectra of Liquids, Solids and Particulates – Polarized light scattering technique, Mueller matrices and Stokes vectors, particle size and optical constants, radiation transfer, absorpiton, spectra of biological systems.

8. Particle Spectroscopy – Mass, charge, velocity, momentum and energy analysis, biological cell sorting.

Knowledge of the fundamental topics covered in this course is necessary for anyone working in astronomy, chemistry, biology, electrical engineering, optical sciences, atmospheric sciences or physics. Throughout the course we decide what instrument and technique is best to make a particular measurement and how to optimize data-taking procedures. Students can suggest what topics they would like covered. Outside lecturers who are experts in a particular area will present several lectures. The grade for the course will be decided from an 80 problem homework set, one short paper and a final oral exam.

Grading Criteria:

  • In order to receive the grade of A in the course, the following must be done:
  1. satisfactorily complete an 85 problem homework set,
  2. write a three-page paper on a topic of the student’s choice related to the course,
  3. pass an oral exam covering the homework problem set.

There will be no quizzes, in-class exams or final exam.

The problems will be due in three parts and handed in on time.

Part 1 – Problems 1-30 due on the class date before October 15,

Part 2 – Problems 31-60 due on the class date before November 30

and lab manual questions

Part 3 – Problems 61-85 due two class periods before the last day of class.

Each problem will receive one of the following grades:

Satisfactory 10 no points off

Should have done better 5 5 points off

Unsatisfactory 0 10 points off

The instructor will grade the problem sets and return them to the students so that they can correct the mistakes and ultimately do satisfactory work on all of them. By the official date of the final exam, all corrected problems should be returned to the instructor for final grading.

The 85 problem homework set is worth 90% of the grade, and the paper and oral exam are worth 10%. Loss of 10 point will be a grade of B, etc. No incompletes are given unless negotiated in advance.

The first homework set will be returned for corrections, the second and third set might not. All problems are due by 5:00 p.m. of the last day of classes. They can be put in the instructor’s mailbox. NOTHING is accepted after that date!

The paper is due on the second to the last week of classes.

  • All students are required to meet with the instructor before the last three weeks of the semester to discuss the problems.

No Textbook required
