DESCRIPTION:Speakers: Pedro Punta de la Herrán (Universidad de Sevilla)\n
 The study of reactions involving weakly bound exotic nuclei is an active f
 ield due to advances in radioactive beam facilities. Many of these nuclei 
 can be approximately described by a model consisting of an inert core and 
 one or more valence nucleons. However\, to properly describe some of these
  nuclei within few-body models\, additional effects must be considered\, s
 uch as deformations and possible excitations of the core. This is the case
  of $^{17}$C and $^{19}$C\, which can be approximately described as a defo
 rmed core and a weakly-bound neutron. \n\nThe carbon isotopes $^{17}$C and
  $^{19}$C are studied using the novel NAMD model resulting from the combin
 ation of the Nilsson and PAMD models from [Phys. Rev. C 108 (2023) 024613]
 . The proposed formalism follow the Nilsson model scheme but including mic
 roscopic information of the core based on Antisymmetrized Molecular Dynami
 cs (AMD) calculations. The bound states wavefunctions obtained for $^{17}$
 C have been already applied to the $^{16}\\text{C}(d\,p)^{17}\\text{C}$ tr
 ansfer reaction\, providing a good agreement with the experimental data fr
 om [Phys. Lett. B 811 (2020) 135939].\n\nThe same transfer reaction is stu
 died also populating unbound states in the continuum of $^{17}$C.\nIn our 
 calculations\, the continuum spectrum of unbound states of the nucleus is 
 discretized using the transformed harmonic oscillator basis (THO) [Phys. R
 ev. C 80 (2009) 054605]\, which has been successfully applied to the analy
 sis of breakup and transfer reactions [Phys. Rev. Lett. 109 (2012) 232502]
 . The unbound states of $^{17}$C and $^{19}$C are also studied in breakup 
 reactions $^{17}\\text{C}(p\,p')^{16}\\text{C}+n$ and $^{19}\\text{C}(p\,p
 ')^{18}\\text{C}+n$. Promising results have been found in the comparison o
 f the XCDCC calculations [Phys. Rev. C 95 (2017) 044611] using the NAMD mo
 del with the experimental data from [Phys. Lett. B 660 (2008) 320].\n\nhtt
