“…The shape of the E1 strength function in 17 Ne is governed by the so-called soft dipole mode (SDM) existing in this nucleus. Properties of the SDM in the three-body systems were investigated in details in the Borromean 2n halo nuclei 6 He and 11 Li [8,9,and Refs. therein].…”

From Coulomb excitation cross sections to nonresonant astrophysical rates in three-body systems: The Ne17 case

Coulomb and nuclear dissociation of 17 Ne on light and heavy targets are studied theoretically. The dipole E1 strength function is determined in a broad energy range including energies of astrophysical interest. Dependence of the strength function on different parameters of the 17 Ne ground state structure and continuum dynamics is analyzed in a three-body model. The discovered dependence plays an important role for studies of the strength functions for the three-body E1 dissociation and radiative capture. The constraints on the [s 2 ]/[d 2 ] configuration mixing in 17 Ne and on pwave interaction in the 15 O+p channel are imposed based on experimental data for 17 Ne Coulomb dissociation on heavy target.

We present an investigation of the structure of 13 Be obtained via a kinematically complete measurement of the (p, pn) reaction in inverse kinematics at 265 MeV/nucleon. The relative energy spectrum of 13 Be is compared to Transfer-to-the-Continuum calculations which use as structure inputs the overlaps of the 14 Be ground-state wave function, computed in a three-body model, with the unbound states of the 13 Be residual nucleus. The key role of neutron p-wave orbital in the interpretation of the low-relative-energy part of the spectrum is discussed.

Recent Progress in Few-Body Physics

Within the hyperspherical harmonics approach the three-body problem is reduced to a motion of one effective particle in a "strongly deformed" field, which is described in coupled-channel formalism. This method is especially suited to studies of phenomena characterized by genuine three-body dynamics, e.g. Borromean haloes and true three-body decays. The reduction of the hyperspherical equations set to a single-channel Schrödinger equation provides the basis for the use of the standard quasiclassical expression for calculations of widths for true three-body decays. We demonstrate that the quasiclassical approach by itself is quite precise in application to typical profiles of the three-body effective potentials. However, the reduction to single-channel formalism leads to significant overestimation of the two-proton width Γ 2p . This is demonstrated by the example of the 17 Ne first excited 3/2 − state decay, questioning, however, the applicability of such an approximation in general.
