The recent announcement of the generation of an isolated single attosecond cycle
pulse,a "spin-off" of strong-field physics, [1],opens the way to a new regime
in ultrafast physics.We will illustrate from numerical solutions of the TDSE
(Time Dependent Schroedinger Equation) attosecond electron response in Enhanced
Ionization ,EI, of H2+ thus elucidating a recent experimental mystery in the
Coulomb Explosion of this system [2], Carrier Envelope Phase,CEP, control of
electron transfer in H3++, [3], where electron trajectories separated by a few
hundreds of attoseconds interfere. Finally we will discuss the usefulness of
photoelectron interferometry with broadbands inherent with attosecond pulses[4].
