ab: Summary: {\it Particle in a Box} is a non-commercial program which was
devised to help students to become familiar with typical quantum
phenomena when they are introduced for the first time in a
physical-chemistry course. Its name comes from the simple and
well-known theoretical model on which it is based. The user can select
three distinct potential wells, namely the one dimensional with two
infinite walls, the one dimensional with one finite barrier and the
two-dimensional infinite potential square box. In order to set the
system conditions, the user may enter the values for different physical
parameters, including the quantum level, mass of the particle,
dimensions of the box and height of the finite potential barrier.
Through a clear and attractive output, one can visualize and compare
the wavefunctions and their squares for the chosen quantum levels, the
corresponding energy diagrams and probabilities of tunneling. The
program was tested as a pedagogical tool in tutorials of an
introductory course in atomic and molecular structure. The use of this
software in the classroom increased the receptivity of the students to
non-intuitive topics such as, for instance, quantization, nodes and
tunneling, which helped to improve their success in the course.
