Father Time. I. Does the Cosmic Microwave Background Radiation Provide a Universal Arrow of Time ?
The existence of a non-thermodynamic arrow of time was demonstrated in a
recent paper (Mod.Phys.Lett. A13, 1265 (1998)), in which a model of non-local
Quantum Electrodynamics was formulated through the principle of gauge
invariance. In this paper we show that the Cosmic Microwave Background
Radiation is capable of making every particle of the universe (except those
which are not acted upon by an electromagnetic field) follow this arrow of
time.Comment: To appear in Mod.Phys.Lett. A. This is a slightly revised version
which has been communicated to the EPS-HEP99 Conference at Tampere, Finland

Dissociative Autoionization in (1+2)-photon Above Threshold Excitation of H2 Molecules
We have theoretically studied the effect of dissociative autoionization on
the photoelectron energy spectrum in (1+2)-photon above threshold
ionization(ATI) of H2 molecules. We have considered excitation from the ground
state X-singlet-Sigma-g+(v=0,j) to the doubly excited autoionizing states of
singlet-Sigma-u+ and singlet-Pi-u+ symmetry, via the intermediate resonant
B-singlet-Sigma-u+(v=5,j) states. We have shown that the photoelectron energy
spectrum is oscillatory in nature and shows three distinct peaks above the
photoelectron energy 0.7 eV. This feature has been observed in a recent
experiment by Rottke et al, J. Phys. B, Vol. 30, p-4049 (1997).Comment: 11 pages and 4 figure
