It is shown that for super intense laser pulses propagating in a hot plasma, the action of the radiation reaction force (appropriately incorporated into the equations of motion) causes strong bulk plasma motion with the kinetic energy raised even to relativistic values; the increase in bulk energy is accompanied by a corresponding cooling (intense cooling) of the plasma. The effects are demonst...

In this work, we examine the geometric character of field equations general relativity and propose to formulate relativistic in terms Riemann curvature tensor. The resulted are also integrated into framework that have presented our previous works all known classical fields can be expressed same dynamical form. We discuss a possibility reformulate so Ricci tensor energy-momentum appear symmetric...

Thermal X-ray emission which is simultaneous with the prompt gamma-rays has been detected for the first time from a supernova connected with a gamma-ray burst (GRB), namely GRB060218/SN2006aj. It has been interpreted as arising from the breakout of a mildly relativistic, radiation-dominated shock from a dense stellar wind surrounding the progenitor star. There is also evidence for the presence ...

Excitation energies of the ns1/2 (n= 7-10), npj (n = 7-9), ndj (n= 6-8), nfj (n= 5-7), and ngj (n= 5-6) states in Th IV are evaluated. First-, second-, third-, and all-order Coulomb energies and firstand second-order Coulomb-Breit energies are calculated. Reduced matrix elements, oscillator strengths, transition rates, and lifetimes are determined for the 96 possible nlj−n′l′ j′ electric-dipole...
