Abstract
In this lecture, I would like to discuss the nuclear aspects of the physics of strong electromagnetic fields. In particular, I shall address the following questions:
-
a)
Is it possible to form giant nuclear molecules (e.g. 238U+238U) with a lifetime of about lO-19 s in a heavy-ion reaction at bombarding energies near the Coulomb barrier?
-
b)
What are the implications of dynamical nuclear alignment (due to Coulomb excitation) for nuclear “sticking”?
The formation of very heavy intermediate nuclear molecules plays a vital role not only for spontaneous positron creation but also for the possible production of light neutral elementary particles (axion) or composite particle (poly-positronium).
