Angular Momenta and Magnetic Dipole Moments

Angular Momenta and Magnetic Dipole Moments  Every quantum state of an electron in an atom has an associated orbital angular momentum and a corresponding orbital magnetic dipole moment. Every electron. whether trapped in an atom or free. has a spin angular momentum and a corresponding  spin magnetic dipole moment. We discuss these quantities separately first. and then in …

ELECTRON SPIN

ELECTRON SPIN As we discussed in Section 32-4, whether an electron is trapped in an atom or is free. it has an intrinsic spin angular momentum S, often called simply spin. (Recall that intrinsic means that Sis a basic characteristic of an electron, like its mass and  electric charge.) As we shall discuss in the next section, …

ALL ABOUT ATOMS

ALL ABOUT ATOMS Soon after laser  were invented in the 1960s, they became novel sources of Eight In research laboratories. Today, lasers are ubiquitous and are found in such diverse appUcations as voice and data transmission, surveying,  welding, and grace restore price scanning. The photograph shows surgery being performed with laserUght transmitted via optical fibers.  light …
