The latter are anomalous gases produced by Hadronic Reactors^TM of molecular type [2] (Patented and International Patents Pending) which expose atoms to the extremely intense electronmagnetic fields existing at atomic distances from electric arcs in such a way to create a toroidal distribution of the orbitals of individual atoms, whether isolated or part of a valence bond. Polarized atoms, dimers and molecules then attract each other via opposing magnetic polarities resulting into stable clusters which constitute a new chemical species called Santilli's magnecules [2]. Some of the numerous open problems in the study of this intriguing new chemical species are pointed out.17 pages, no eps-figuresGeneral Physicstext
