“…In this study, they have observed large reaction cross section value for 37 Mg as compared to other isotopic chain and consequently predicted 37 Mg to have a halo structure. In another study S. Watanabe [11] concluded from their fully microscopic double folding frame work with the AMD densities, that 37 Mg exhibits deformed halo structure. In our earlier work we explored the structure of some isotopes of Ne, Mg and Si [12].…”

“…The halo structure originates due to extremely weak bound nucleons which decouple from the nuclear core. The interaction cross sections of such nuclei like 6,8 He, 11 Li and 11,14 Be [1] are anomalously high due to large magnitude of consolidated root mean square (rms) radii. The one neutron/proton breakup of halo projectiles with stable target at near/far barrier energies is one of the tool to investigate the structure of such systems [2].…”

We have studied the ground state properties (binding energy and charge radius) using relativistic mean filed formalism (RMF) for Mg-isotopes in the valley of stability to drip line region. The RMF densities have been analyzed in context of reaction dynamics. The calculated results of 24−40 Mg+ 12 C reactions at projectile energy 240 AMeV using Glauber model with the conjunction of densities from relativistic mean field formalism are compared with experimental data. We found remarkable agreement of estimated values of reaction cross sections with experimental data except for 37 Mg isotope. In view of this, the halo status of 37 Mg is examined through higher magnitude of rms radius and small value of longitudinal momentum distribution. Finally, an effort is made to explore the structure of 37 Mg halo candidate using Glauber few body formalism.PACS numbers: 25.60. Pj, 25.70.Gh, 25.70.Jj, 27.90.+q I.

The effects of deformation and orientation on the nucleus–nucleus and proton–nucleus reaction cross-sections are investigated at intermediate and high energies, in the framework of the Coulomb modified Glauber model. The matter density of the projectile is treated by a deformed Fermi shape with quadrupole and hexadecapole deformations. In-medium effects are included through a local density- and an energy-dependent effective nucleon–nucleon total cross-section. Calculations are performed for the deformed projectiles [Formula: see text] colliding by [Formula: see text] and by protons. It is found that the average of reaction cross-section over all directions of the symmetry axis of the deformed projectile differs by about 2[Formula: see text] compared with that calculated for a spherical projectile with the same rms matter radius as the deformed one. The difference between the cross-sections calculated with and without medium effects is of the order 2[Formula: see text] for both deformed and spherical cases. The integrated reaction cross-sections over all orientation angles provide a consistent explanation of the experimental data. The orientation of the heavy projectile can produce a difference in the calculated cross-section about 35[Formula: see text] for nucleus–nucleus and about 45[Formula: see text] for proton–nucleus. This study is also useful for experiments of polarized beams that have created opportunities to study oriented collisions of deformed nuclei. The method is applied to extract the rms radius of [Formula: see text] and it is found to be about 3.56 and 3.45[Formula: see text]fm when using deformation with and without in-medium effects.
