✦ Synopsis

A lower hybrid current drive model which takes into account a dc electric field has been developed. The model is based on the Fokker-Planck equation, plasma circuit equation and power balance equations. Simulation results qualitatively agree well with those of the experiments.

The electric field effect on the UV decomposition of ketene was studied. The ratio of the main products [&H.,] / [C2Hs] which is proportional to [ CH2( 'A, ) ] / [CH2 ('B, ) ] 2 was measured as a function of pressure and as a function ofthe electric field strength in the range O-5 kV/cm.

We present a numerical study based on a Monte Carlo algorithm of the magnetic properties of a mixed Ising ferrimagnetic model on a cubic lattice where spins s AE1=2 and spins S 0; AE1 are in alternating sites on the lattice. We carried out exact ground state calculations and employ a Monte Carlo sim

It is argued that under the conditions of current experimental interest, one role of a weak electrical dc field on the dynamics of a high Rydberg molecular electron is to stretch the time axis. The stretch factor is essentially independent of the field and provides a classical analog of the quantum
