Fusion of Halo Nucleus 6he on 238u :Evidence for Tennis-Ball (Bubble) Structure of the Core of the Halo (Even the Giant-Halo) Nucleus

Authors: Syed Afsar Abbas

In a decade-and-a-half old experiment, Raabe et al.(Nature 431 (2004) 823), had studied fusion of an incoming beam of halo nucleus 6He with the target nucleus 238U . We extract a new interpretation of the experiment, different from the one that has been inferred so far. We show that their ex- periment is actually able to discriminate between the structures of the target nucleus (behaving as standard nucleus with density distribution described with canonical RMS radius r = r0 A1/3 with r0 = 1.2 fm), and the ”core” of the halo nucleus, which surprisingly, does not follow the standard density distribution with the above RMS radius. In fact the core has the structure of a tennis-ball (bubble) like nucleus, with a ”hole” at the centre of the den- sity distribution. This novel interpretation of the fusion experiment provides an unambigous support to an almost two decades old model (Abbas, Mod. Phys. Lett. A 16 (2001) 755), of the halo nuclei. This Quantum Chro- modyanamics based model, succeeds in identifyng all known halo nuclei and makes clear-cut and unique predictions for new and heavier halo nuclei. This model supports, the existence of tennis-ball (bubble) like core of even the giant-neutron halo nuclei. This should prove beneficial to the experimen- talists, to go forward more confidently, in their study of exotic nuclei.
