Study of clustering, pairing and resonances in direct nuclear reactions

684-689At energies from about 10 MeV to 100’s of MeV the light incident projectiles incident on medium heavy targets produce nuclear reactions which normally come under the category of direct reactions. At such energies one can study the microscopic structure of nuclei because the wave length is comparable to the inter nucleon separations in nuclei. Besides the normal independent particle behavior one can study the influences of the short range and long range residual interactions in the form of pairing and clustering in nuclei. The resonances existing as the molecular nuclear structures comprising of 12C-12C and 16O-8Be structure in 24Mg* has given rise to interesting phenomenon of perturbing resonances in heavy cluster knockout reactions
