نویسنده
چکیده
The coupling of the breathing and rotational modes of the skyrmionskyrmion system leads to a nucleon-nucleon spin-orbit interaction of short range, as well as to spin-orbit potentials for the transitionsNN → N(1440)N , NN → NN(1440) and NN → N(1440)N(1440). The longest range behaviour of these spin-orbit potentials is calculated in closed form. Preprint HU-TFT-96-57

Microscopic Combinatorial approach is used to calculate the state and level densities with fixed exciton numbers, in some actinide nuclei. Deformed Saxon-Woods shell model was used as a basis from which all posible configurations were generated. The pairing interaction was taken into account by applying the BCS theory to each configurations. Both the spin and parity distributions were obtained,...

We discuss the computation of two-body matrix elements from the Argonne v 18 interaction. The matrix elements calculation is presented both in particle-particle and in particle-hole angular momentum coupling. The procedures developed here can be applied to the case of other NN potentials, provided that they have a similar operator format.

We calculate the cross sections of the elastic and inelastic breakup modes for the inclusive breakup reaction 28 Si(8 B, 7 Be) at beam energies between 10-40 MeV/nucleon within a direct fragmentation model formulated in the framework of the post form distorted-wave Born-approximation. In contrast to the case of the stable isotopes, the inelastic breakup mode is found to contribute only up to 30...

We argue that nuclei are not transparent for fast projectile partons. Color transparency is effective for final state interactions in heavy particle production, though nuclear filtering of initial partons can reduce the cross sections. We show that short-ranged initial state interactions, which have been neglected so far, can be important in hadroproduction. With the present scenario of hadropr...
