“…However, to the best of our knowledge, this is the first time that the effect of the deformation is considered also on the radial form factor of the transfer reaction for exotic nuclei and, not only, for the calculation of the corresponding spectroscopic factor. As already shown in stable nuclei [15], there is a non-negligible effect on the radial extension of the form factor due to the deformation. One can only expect this effect to increase considerably in the case of halo nuclei.…”

Background: Reactions with halo nuclei from deformed regions exhibit important deviations from the inert core + valence picture. Structure and reaction formalisms have recently been extended or adapted to explore the possibility of exciting the underlying core. Purpose: We will study up to what extent transfer reactions involving halo nuclei 11 Be and 17 C can be reproduced with two different models that have previously shown a good success reproducing the role of the core in light halo nuclei. Methods: We focus on the structure of 11 Be and 17 C with two core + valence models: Nilsson and a semimicroscopic particle-rotor model using antisymmetrized molecular dynamic calculations of the cores. These models are later used to study 16 C(d, p) 17 C and 11 Be(p, d ) 10 Be transfer reactions within the adiabatic distorted wave approximation. Results are compared with three different experimental data sets. Results: A good reproduction of both the structure and transfer reactions of 11 Be and 17 C is found. The Nilsson model provides an overall better agreement for the spectrum and reactions involving 17 C while the semimicroscopic model is more adequate for 11 Be, as expected, since the 17 C core is closer to an ideal rotor. Conclusions: Both models show promising results for the study of transfer reactions with halo nuclei. We expect that including microscopic information in the Nilsson model, following the spirit of the semimicroscopic model, can provide a useful, yet simple framework for studying newly discovered halo nuclei.

“…In order to obtain the correct binding energy, the depth of the deformed well must finally be adjusted. This may not cause further problem, however, the iteration-relaxation method itself does not always converge to the desired solution, as reported e.g., by Broad et al [16]. This seems to be a general problem with these types of methods, since it is very difficult to design such a procedure so as to converge toward a specified solution, unless either the distance between eigenvalues is large or only the solution of a given type (say given k) with the lowest number of nodes is sought (compare also the difficulties reported by Kawai and Yazaki [17]).…”

“…In this connection it must be noted that it is characteristic of well deformed nuclei that the level separations are not all large. The orbital reported in [16] A method of solving the problem of eigenstates in a deformed well, which is similar to the present one is that of using the Kapur-Peierls eigenstates with a spherical problem as expansion basis. These states are solutions of…”

“…b) Our next example is the 7/2 (523) proton orbital in the lower rare-earth region, belonging to the fan of deformed orbitals stemming from l h ~ 1/2. Broad et al [16] have calculated this orbital using the relaxation method. Regrettably the figure of the radial multipole functions shown in their paper does not allow for a very detailed comparison.…”
