dc.description.abstract | Background: Lying at the lower edge of the “island of inversion,” neutron-rich fluorine isotopes (
29
–
31
F
) provide a curious case to study the configuration mixing in this part of the nuclear landscape. Recent studies have suggested that a prospective two-neutron halo in the dripline nucleus
31
F
could be linked to the occupancy of the
p
f
intruder configurations.
Purpose: Focusing on configuration mixing, matter radii, and neutron-neutron (
n
n
) correlations in the ground state of
31
F
, we explore various scenarios to analyze its possible halo nature as well as the low-lying electric dipole (
E
1
) response within a three-body approach.
Method: We use an analytical, transformed harmonic oscillator basis under the aegis of a hyperspherical formalism to construct the ground-state three-body wave function of
31
F
. The
n
n
interaction is defined by the Gogny-Pires-Tourreil potential that includes the central, spin-orbit, and tensor terms, while the different two-body potentials to describe the core
+
n
subsystems are constrained by the different possible scenarios considered.
Results: The
31
F
ground-state configuration mixing and its matter radius are computed for different choices of the
30
F
structure coupled to the valence neutron. The admixture of
p
3
/
2
,
d
3
/
2
, and
f

/
2
components is found to play an important role, favoring the dominance of inverted configurations with dineutron spreads for two-neutron halo formation. The increase in matter radius with respect to the core radius,
Δ
r
≳
0.30 fm and the dipole distributions along with the integrated
B
(
E

)
strengths of

are large enough to be compatible with other two-neutron halo nuclei. | es |
