Trent University: PHYS 2620H – Atomic, Molecular and Nuclear Physics DEPARTMENT OF PHYSICS & ASTRONOMY PHYS 2620H - ATOMIC, MOLECULAR AND NUCLEAR PHYSICS 2015WI Instructor: Professor Ralph Shiell Email: [email protected] Telephone: Ext. 7023 Campus: Peterborough Office Location Location: Science Complex 213 Office Hours: Weds 13:00 – 14:00 Secretary: Gina Collins Email: [email protected] Telephone: Ext. 7715 1. Course Description electron atoms, magnetic dipole moments and spin, transitions and selection Quantum mechanics of one-electron rules, identical particles, excited states of atoms, molecules, nuclear and particle physics. Prerequisites: PHYS 2610H: Introductory Quantum Physics PHYS–MATH 2150H 50H: Ordinary differential equations MATH 2110H: Calculus II: Calculus of several variables 2. Course Timetable Type Day Time Location Lecture Lecture Seminar (~bi-weekly) Labs Mondays Wednesdays Wednesdays Fridays 12:00-13:50 12:00-12:50 15:00-15:50 13:00-16:00 SC 317 SC 317 SC 317 SC127 The lab sessions will be led by Dave Marshall ([email protected], SC 319, x7461)) 3. Required Text and Course Materials Required: R. Harris, Modern Physics,, 2nd Edition, Pearson, 2007 [If you want a more introductory text… Randall D. Knight, Physics for Scientists and Engineers: A Strategic Approach Approach,, Addison Wesley If you want to know more… P. W. Atkins, Molecular Quantum Mechanics Oxford University Press] Course webpage: http://www.trentu.ca/physics/rshiell/PHYS2620Hdir/PHYS2620H.html Some assignment questions during the semester will require some programming (I recommend either Excel or MATLAB for these. Introductory nnotes for MATLAB can be found on the course webpage). webpage 1 Trent University: PHYS 2620H – Atomic, Molecular and Nuclear Physics 4. Learning Outcomes Upon successful completion of this course, a student should: 1. understand wavefunctions and Schrödinger’s equation, with the quantum harmonic oscillator as an example 2. appreciate the physics underpinning the non-relativistic understanding of the hydrogen atom 3. be able to calculate the expectation value of angular momentum components, and their connection with magnetic dipole moments and the Stern-Gerlach experiment 4. quantitatively understand the spin-orbit interaction, and qualitatively explain multielectron atomic structure and the periodic table 5. understand electric dipole transitions between energy levels 6. be able to explain the rotational, vibrational and electronic structure of molecules 7. understand the trends of nuclear sizes, binding energies, and perform calculations using the semiempirical mass model, shell model and nuclear decay 5. Course Evaluation Type of Assessment In-class quizzes Assignments Laboratory Weighting 5% 15% 25% Midterm Exam Final Exam 20% 35% When ~bi-weekly ~bi-weekly ~ bi-weekly; timetable arranged with Dave Marshall Monday Feb 9 April exam period The in-class quizzes include short questions based on the readings. The assignments comprise a variety problems, with some programming required (typically in Excel or MatLab). The midterm and final exam will typically contain a mix of short- and long-answer questions. Note: Regardless of the overall grade calculated above, an average of at least 40% on the test and final exam, weighted as above, must be obtained in order to pass this course. Otherwise a maximum grade of 45% (i.e. an F) will be assigned. Late policy: problem sets that are late without a good reason provided in advance of their respective deadline will be subject to a 10% reduction in marks for each two working-day period for which they are late. 6. Class Format and Ordering of Topics Each week, pre-class reading will be assigned from the textbook, and there will be quizzes at the beginning of some classes based on these readings. I will then summarize the main points of the reading, and we will work in small groups on short, ungraded assignments designed to develop a strong understanding of the material. Take-home assignments requiring more in-depth quantitative analysis will be submitted for marking. The seminars (~bi-weekly) will review assignments after they are marked and handed back. The schedule of topics is listed below: Although specific dates are not listed, I will follow the order of topics as given and will regularly communicate in class and on the learningSystem/Blackboard about the pacing of the lectures. For this reason, it is important for you to attend class and log on to the learningSystem/Blackboard regularly. 2 Trent University: PHYS 2620H – Atomic, Molecular and Nuclear Physics We follow Chapters 5, 7, 8, 10, 11 of Harris: 1. 2. 3. 4. 5. 6. 7. Review of PHYS 2610H (wavefunctions, Schrödinger’s equation, simple harmonic oscillator) Atoms I (the hydrogen atom) Angular momentum and magnetic dipole moments Atoms II (spin-orbit interaction, multielectron atoms, periodic table) Transitions between energy levels (electric dipole moment, selection rules, lasers) Molecules (rotational, vibrational and electronic structure) Nuclei (sizes, binding energies, semi-empirical mass model, shell model, nuclear decay) University Policies 1. Academic Integrity Academic dishonesty, which includes plagiarism and cheating, is an extremely serious academic offence and carries penalties varying from failure on an assignment to expulsion from the University. Definitions, penalties, and procedures for dealing with plagiarism and cheating are set out in Trent University’s Academic Integrity Policy. You have a responsibility to educate yourself – unfamiliarity with the policy is not an excuse. You are strongly encouraged to visit Trent’s Academic Integrity website to learn more: www.trentu.ca/academicintegrity. 2. Access to Instruction It is Trent University's intent to create an inclusive learning environment. If a student has a disability and/or health consideration and feels that he/she may need accommodations to succeed in this course, the student should contact the Student Accessibility Services Office (SAS), (BH Suite 132, 705-748-1281 or email [email protected]).
