Banerjee, S. N.; Chakraborty, S. N. – American Journal of Physics, 1980
Presents the outline of an approach related to the teaching of the chapter on bound and scattering states in a short-range potential, which forms a standard part of an undergraduate quantum mechanics course or nuclear physics course. (HM)

Griffin, Donald C.; McGhie, James B. – American Journal of Physics, 1973
Discusses an interactive computer algorithm which allows beginning students to solve one- and three-dimensional quantum problems. Included is an example of the Thomas-Fermi-Dirac central field approximation. (CC)

Schneider, Mark B. – Physics Teacher, 2010
The past two decades of attention to introductory physics education has emphasized enhanced development of conceptual understanding to accompany calculational ability. Given this, it is surprising that current texts continue to rely on the Bohr model to develop a flawed intuition, and introduce correct atomic physics on an ad hoc basis. For…

Quijas, P. C. Garcia; Aguilar, L. M. Arevalo – European Journal of Physics, 2007
Recently, there have been many efforts to use the research techniques developed in the field of physics education research to improve the teaching and learning of quantum mechanics. In particular, part of this research is focusing on misconceptions held by students. For instance, a set of misconceptions is associated with the concept of stationary…

Cox, Timothy; Lekner, John – European Journal of Physics, 2008
Exact closed-form solutions of the time-dependent Schrodinger equation are obtained, describing the propagation of wavepackets in the neighbourhood of a potential. Examples given include zero reflection, total reflection and partial reflection of the wavepacket, for the sech[superscript 2]x/a, 1/x[superscript 2] and delta(x) potentials,…

Sommerfeld, Thomas – Journal of Chemical Education, 2011
The quantum semester of a typical two-semester physical chemistry course is divided into two parts. The initial focus is on quantum mechanics and simple model systems for which the Schrodinger equation can be solved in closed form, but it then shifts in the second half to atoms and molecules, for which no closed solutions exist. The underlying…

Pronchik, Jeremy N.; Williams, Brian W. – Journal of Chemical Education, 2003
Describes an alternative approach to finding exactly solvable, one-dimensional quantum mechanical potentials. Differs from the usual approach in that instead of starting with a particular potential and seeking solutions to the related Schrodinger equations, it begins with known solutions to second-order ordinary differential equations and seeks to…

Ercolani, Gianfranco – Journal of Chemical Education, 2005
The finite-difference boundary-value method is a numerical method suited for the solution of the one-dimensional Schrodinger equation encountered in problems of hindered rotation. Further, the application of the method, in combination with experimental results for the evaluation of the rotational energy barrier in ethane is presented.

Ceccarelli, Leah – Technical Communication Quarterly, 1994
Argues that, by identifying physicist Erwin Schrodinger's book "What is Life?" as inspirational community-forming discourse, it is possible to recognize the rhetorical artistry of his negotiation between two audiences. Notes that the book builds common ground, applies productive ambiguity at a key point of collision, and skillfully…

Summers, M. K. – Physics Education, 1976
Discusses the analog simulation of several quantum mechanical problems, including the Schrodinger equation and the de Broglie relation. (MLH)

Boykin, Timothy B.; Luisier, Mathieu; Klimeck, Gerhard – European Journal of Physics, 2010
Discrete approaches have long been used in numerical modelling of physical systems in both research and teaching. Discrete versions of the Schrodinger equation employing either one or several basis functions per mesh point are often used by senior undergraduates and beginning graduate students in computational physics projects. In studying…

Ellison, Mark D. – Journal of Chemical Education, 2008
The one-dimensional particle-in-a-box model used to introduce quantum mechanics to students suffers from a tenuous connection to a real physical system. This article presents a two-dimensional model, the particle confined within a ring, that directly corresponds to observations of surface electrons in a metal trapped inside a circular barrier.…

Brandhorst, Kai; Grunenberg, Jorg; Tamm, Matthias – Journal of Chemical Education, 2008
A new set of d orbitals, constructed as a linear combination of the omnipresent set of d[subscript xy], d[subscript yz], d[subscript xz], d[subscript x[superscript 2]-y[superscript 2]], and d[subscript z[superscript 2]] orbitals, is suitable for the discussion of octahedral transition-metal complexes. The main feature of the newly derived set…

Stefani, Christina; Tsaparlis, Georgios – Journal of Research in Science Teaching, 2009
We investigated students' knowledge constructions of basic quantum chemistry concepts, namely atomic orbitals, the Schrodinger equation, molecular orbitals, hybridization, and chemical bonding. Ausubel's theory of meaningful learning provided the theoretical framework and phenomenography the method of analysis. The semi-structured interview with…
