CHAPTER 11 The photoelectric effect
... By the latter half of the nineteenth century, the ability of Newtonian mechanics to predict and explain much of the material world was unquestioned. At the same time, discoveries in chemistry showed that the world consisted of many elements, each made up of identical atoms, and compounds made up of ...

4.2 The Structure of an Atom
... Isotopes are atoms of the same element that have different numbers of neutrons and different mass numbers. To distinguish one isotope from another, the isotopes are referred by their mass numbers. For example, oxygen has 3 isotopes: oxygen-16, oxygen-17, and oxygen-18. All three oxygen isotopes can ...

beaming, synchrotron and inverse compton
... radial, like in gamma–ray bursts. In this case, assume that the plasma is contained in a conical narrow shell (width smaller than the distance of the shell from the apex of the cone). The observer which is moving together with a portion of the plasma, (the nearest case of a “comoving observer”) will ...

Introduction to Particle Physics
... A star's distance can be estimated from its brightness as seen on Earth, if its total emitted light is known — the farther away it is, the dimmer it appears. Accurate estimates of total emitted light are possible for only a few kinds of astronomical objects such as type Ia supernovae most distant su ...

The two-dimensional hydrogen atom revisited
... A semiconductor quantum well under illumination is a quasi-two-dimensional system, in which photoexcited electrons and holes are essentially confined to a plane. The mutual Coulomb interaction leads to electron–hole bound states known as excitons, which are extremely important for the optical proper ...
