  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.
