Kinetic energy defined

Fig. 1.10. The two graphs both show the mean photoelectron kinetic energy, defined as center of gravity of the recorded 2PPS spectra, plotted (a) as a function of the size of the clusters deposited under soft-landing conditions (3eV per cluster) and (b) as a function of the deposition energy for Agg+ clusters [93]. The corresponding photoelectron spectra were obtained with two 150 fs pulses of 3.2 eV photon energy each. The temperature in all experiments was 100K. No diffusion of the clusters is observed at this temperature on HOPG... Fig. 1.10.

Physics. Lithium, beryllium, boron, sodium, and a number of other elements, each have an isotope that, upon capturing a thermal neutron, undergoes an exoerglc reaction. These reactions produce energetic charged particles, either a proton or an alpha particle depending upon the isotope, and a recoil particle. Each particle emitted has a specific kinetic energy defined by the Q-value of the reaction which in turn serves to identify the element. For the case of lithium. [Pg.164]

If the adiabatic work is independent of the path, it is the integral of an exact differential and suffices to define a change in a function of the state of the system, the energy U. (Some themiodynamicists call this the internal energy , so as to exclude any kinetic energy of the motion of the system as a whole.)... [Pg.330]

Classical ion trajectory computer simulations based on the BCA are a series of evaluations of two-body collisions. The parameters involved in each collision are tire type of atoms of the projectile and the target atom, the kinetic energy of the projectile and the impact parameter. The general procedure for implementation of such computer simulations is as follows. All of the parameters involved in tlie calculation are defined the surface structure in tenns of the types of the constituent atoms, their positions in the surface and their themial vibration amplitude the projectile in tenns of the type of ion to be used, the incident beam direction and the initial kinetic energy the detector in tenns of the position, size and detection efficiency the type of potential fiinctions for possible collision pairs. [Pg.1811]

The effective nuclear kinetic energy operator due to the vector potential is formulated by multiplying the adiabatic eigenfunction of the system, t t(/ , r) with the HLH phase exp(i/2ai ctan(r/R)), and operating with T R,r), as defined in Eq. fl), on the product function and after little algebraic simplification, one can obtain the following effective kinetic energy operator. [Pg.45]

Techniques have been developed within the CASSCF method to characterize the critical points on the excited-state PES. Analytic first and second derivatives mean that minima and saddle points can be located using traditional energy optimization procedures. More importantly, intersections can also be located using constrained minimization [42,43]. Of particular interest for the mechanism of a reaction is the minimum energy path (MEP), defined as the line followed by a classical particle with zero kinetic energy [44-46]. Such paths can be calculated using intrinsic reaction coordinate (IRC) techniques... [Pg.253]

The present perturbative beatment is carried out in the framework of the minimal model we defined above. All effects that do not cincially influence the vibronic and fine (spin-orbit) stracture of spectra are neglected. The kinetic energy operator for infinitesimal vibrations [Eq. (49)] is employed and the bending potential curves are represented by the lowest order (quadratic) polynomial expansions in the bending coordinates. The spin-orbit operator is taken in the phenomenological form [Eq. (16)]. We employ as basis functions... [Pg.533]
