Systematic Analysis of Total Reaction Cross Sections of Unstable Nuclei with Glauber Theory

Reaction cross sections for 11 Be and 8 B on proton targets at 40A - 120A MeV have been measured by the transmission method. With these data, we can discuss the proton- and neutron- density distributions at the nuclear surface independently in principle using the Glauber theory. Our experimental results support that the constituent of halo in 11 Be is neutron dominantly and that of 8 B is proton dominantly.

Reaction Cross Sections

Working within the framework of Coulomb modified Glauber theory, we calculate α particle total reaction cross sections for 12 C , 16 O , 28 Si , 40,48 Ca , 58,60 Ni and 124 Sn at medium energies in the rigid projectile model using the parameters of the phenomenological N–α amplitude. A comparison with the available experimental data shows that, in general, the results of the present calculation are in much better agreement with the data compared to those of the optical limit calculation using the free NN total cross sections.

Reaction Cross Sections

We investigated the reaction dynamics induced by the 7Be,8B+208Pb collisions at energies around the Coulomb barrier. Charged particles originated by both the col- lisions were detected by means of 6 ΔE-Eres telescopes of a newly developed detector array. Experimental data were analysed within the framework of the Optical Model and the total reaction cross-sections were compared together and with the 6,7Li+208Pb colli-sion data. According to the preliminary results, 7Be nucleus reactivity is rather similar to the 7Li one whereas the 8B+208Pb total reaction cross section appears to be much larger than those measured for reactions induced by the other weakly-bound projectiles on the same target.
