free electron - electron that is not attached to an atom or ion or molecule but is free to move under the influence of an electric field lepton - an elementary particle that participates in weak interactions; has a baryon number of 0 photoelectron - an electron that is emitted from an atom...

(38) is forbidden, i.e., that muon and electron neutrinos are different particles. To explain the results of the Brookhaven and other experiments, it is necessary to introduce two conserved lepton numbers: the electron lepton number Le and the muon lepton number Lμ. The electron and muon ...
9.3.2.1 Electron Effective Mass Determination In the framework of the BAC model the electron effective mass equals (9.16)1mc*=12mM[1=EM−EN(EM−EN)2+4XCNM2] where mM is the electron effective mass in the host matrix (i.e. GaInAs compound). According to Eq. (9.16) an increase in...
The main purpose of this paper is to provide an effective procedure to study rigorously the relationship between unipolar and bipolar Euler-Poisson systems in the perspective of mass. Based on the fact that the mass of an electron is far less than that of an ion, we amplify this property by...

although the production probability rapidly decreases with the number of removed nucleons23. Owing to the high kinetic energies, the reaction fragments emerged from the target as fully stripped bare nuclei24,25. The fragments of interest were separated in flight from the remaining primary beam and ...

Therefore, from all of the recent examples of modeling and observations of circumstellar disks a number of mechanisms can be considered that might contribute to very early heating and depletion of moderately volatile elements at 1 AU. However, some of these are localized processes and the timescale...
Field Ionisation (FI) When molecules passing through a very high electric field are ionised by removal of an electron via quantum tunnelling to produce an M+ molecular ion with very little associated fragmentation High-energy CID Typically refers to energy above 1 keV, and can be achieved on mu...
