Abstract

We investigate the interplay of the nuclear and Coulomb interaction in the fragmentation of relativistic 11Li projectiles incident on several targets. The 11Li nucleus is assumed to have a cluster-like structure, with a (bound) di-neutron system coupled to a 9Li core in an s-state. The obtained nuclear cross sections show marked differences with the “experimental” data. Taking the calculated nuclear contribution at face value results in a Coulomb dissociation cross section, σC, which is well reproduced by recent modified-RPA calculation. The pure cluster model then overestimates σC by about 20%.

      Furthermore, in these studies the emphasis was more on investigating the dynamics of the Coulomb breakup process and less on probing the structure of the projectile ground state, which was assumed to have some very simple zero range form. Similar assumption for the projectile structure was also made in other semiclassical calculations [155,156] and also in those based on the prior-form distorted wave Born approximation [157]. In Ref. [158] a theoretical framework has been presented to describe the pure Coulomb breakup of one-neutron halo nuclei within the post-form DWBA where finite range effects are included via a local momentum approximation (LMA) [159–161].

      From the theoretical point of view, the first model calculations for halo nuclei were made by the same authors of Ref. [51] using the sudden approximation and a method based on the Coulomb excitation theory of Adler and Winther [98]. A large number of publications exists dealing with either nuclear or Coulomb breakup [99–230]. For example theoretical models for the neutron angular distribution observable were introduced in [99,122] and [123].
