Momentum kinetic energy

According to the correspondence principle as stated by N. Bohr (1928), the average behavior of a well-defined wave packet should agree with the classical-mechanical laws of motion for the particle that it represents. Thus, the expectation values of dynamical variables such as position, velocity, momentum, kinetic energy, potential energy, and force as calculated in quantum mechanics should obey the same relationships that the dynamical variables obey in classical theory. This feature of wave mechanics is illustrated by the derivation of two relationships known as Ehrenfest s theorems. 

In this chapter the principles of various mass analyzers were enumerated. The function of a mass analyzer is to disperse all ions (in space, time, or frequency) in terms of their miq ratio. This work is accomplished by manipulating their momentum, kinetic energy, and velocity. Magnetic-sector instruments are one... 

Energy Add up momentum, kinetic energy, potential energy, enthalpy, work, friction, and amps. The sum of all these is the total energy of the system. The total energy of the system remains constant when one sort of energy is transformed to another type. 

As mentioned previously, the constant o corresponds to some physically observable quantity such as position, momentum, kinetic energy, or total energy of the system, and it is called the expectation value. Since the expression in Equation 2-22 is being integrated over all space, the value obtained for the physically observable quantity corresponds to the average value of that quantity. This leads to the fourth postulate of quantum mechanics. 

In the FFR of the sector mass spectrometer, the unimolecular decomposition fragments, and B, of tire mass selected metastable ion AB will, by the conservation of energy and momentum, have lower translational kinetic energy, T, than their precursor ... 

The potential energy part is diagonal in the coordinate representation, and we drop the hat indicating an operator henceforth. The kinetic energy part may be evaluated by transfonning to the momentum representation and carrying out a Fourier transform. The result is... 

Free Panicle in ID. The Hamiltonian consists only of the kinetic energy of the particle having mass m ([237] Section 28, [259]). The (unnormalized) energy eigenstates labeled by the momentum index k aie... 

Again, the rotational kinetic energy, which is the full rotational Hamiltonian, can be written in terms of the total rotational angular momentum operator J2 and the component of angular momentum along the axis with the unique principal moment of inertia ... 

There are cases in which the angular momentum operators themselves appear in the Hamiltonian. For electrons moving around a single nucleus, the total kinetic energy operator T has the form ... 

Accelerating voltage (high voltage) scan. An alternative method of producing a momentum (mass) spectrum in magnetic-deflection instruments. This scan can also be used, in conjunction with a fixed radial electrical field, to produce an ion kinetic energy spectrum.
