DESCRIPTION:Speakers: Alla Demyanova (NRC Kurchatov Institute\, 1\, Akadem
 ika Kurchatova pl.\, Moscow\, 123182\, Russia)\nNew differential cross sec
 tions for the single proton transfer reaction $^{13}$C(d\,p)$^{14}$C at a 
 deuteron energy of 18 MeV are presented for the ground state 0+ and three 
 excited states: 6.094 MeV (1$^−$)\; 6.728 MeV (3$^-$)\; 7.341 MeV (2$^
 −$) of the product nucleus. The experimental measurements were carried o
 ut at the U 150M isochronous cyclotron of the Institute of Nuclear Physics
  in Almaty. The analysis of the obtained data\, together with previously p
 ublished results\, was carried out within the framework of the distorted w
 ave method with a finite interaction radius (FRDWBA)\, using precisely sel
 ected parameters of local optical potentials.\n\nBased on a phenomenologic
 al approach\, the values of nuclear vertex constants (NVCs) for the excite
 d states of the 14C nucleus were experimentally determined for the first t
 ime. The NVC value for the ground state demonstrated excellent agreement w
 ith independent theoretical calculations. Modeling of angular distribution
 s showed a high quality of the experiment description in the region of for
 ward angles (up to 60°)\, which confirms the reliability of the proposed 
 methodology. \n\nAnalysis of radial dependencies revealed important struct
 ural features of the exotic states of the $^{14}$C nucleus. It was found t
 hat the form factor of the excited state 1$^−$ (6.094 MeV) has a nodal s
 tructure that is fundamentally different from the behavior of the ground s
 tate. Furthermore\, increased root mean square radii were observed for all
  the investigated excited levels\, which directly indicate an excessive sp
 atial extent of nuclear matter and is a clear sign of the formation of a n
 eutron halo.\n\nhttps://indico.particle.mephi.ru/event/626/contributions/6
