The theory for the determination of relative mass from darkfield electron micrographs is derived, and its limitations are indicated. For our geometry of darkfield apertures and at a beam voltage of 80 kV, a linear relationship between the scattering mass density and the density on the photographic...

The factors of effective mass and charge density cancel leaving an expression comprising only the macroscopic system parameters. This is to be expected as a circuit analysis in terms of a capacitance and inductance can also be used to formulate the problem. However, such an approach can obscure ...

Density functional calculations (B3LYP/6-31G*) have been carried out for cyclopropanone and the singlet and triplet electronic states of oxyallyl, as well as for several bicyclic systems that incorporate the cyclopropanone ring. The results of these calculations, when compared to those obtained with...
The higher the mass of the particle, the narrower the dose-weighted lineal energy spectra and the larger the shift to high lineal energy values. A shift of the spectra in high y values would represent an increase in the aggressiveness of the event, i.e. inducing more frequently lethal ...
