- Isotopes of helium - Wikipedia
Helium (2 He) (standard atomic weight: 4 002 602(2)) has nine known isotopes, but only helium-3 (3 He) and helium-4 (4 He) are stable [4] All radioisotopes are short-lived; the longest-lived is 6 He with half-life 806 92 (24) milliseconds
- Three-body breakup of 6He and its halo structure
In either interpretation, the current results show evidence of the dineutron spatial correlation in 6 He Neutron halo is an intriguing quantum tunneling phenomenon observed in nuclei when we approach the neutron dripline
- Helium-6 - isotopic data and properties - ChemLin
Properties and data of the isotope 6 He See also: list of Helium isotopes Half-life T ½ = 806 7 (15) ms respectively 8 067 × 10-1 seconds s Direct parent isotopes are: 7 He, 11 Li The following table shows the atomic nuclei that are isotonic (same neutron number N = 4) and isobaric (same nucleon number A = 6) with Helium-6
- [2409. 03074] Three-body model of $^ {6}$He with non-local halo . . .
We use hyperspherical coordinates in combination with the Lagrange-mesh technique to compute the ground state energy, root mean square radius and the E1 strength distribution of 6 He We also introduce a three-body interaction to eliminate dependencies on the cutoff parameter of the two-body potentials on the ground state energy

- ^{6}He nucleus in halo effective field theory - Physical Review Link . . .
Purpose: Systems with widely separated intrinsic scales are well suited to an EFT treatment The Borromean halo nucleus 6He exhibits such a separation of scales In this work an EFT in which the degrees of freedom are the valence neutrons (n) and an inert 4He-core ( ) is employed
- Investigation of 6He cluster structures
The 6He( p, t)4He reaction at 150 MeV has been investi-gated at GANIL to provide insight on the 6He cluster structure: the α +2n and t+t configurations The transfer differential cross section were measured with the SPEG spectrometer coupled to the MUST array
- Three-body breakup of 6He and its halo structure - ResearchGate
The Borromean halo nucleus ⁶He has been studied by a kinematically complete measurement of Coulomb and nuclear breakup into α + 2n on Pb and C targets at 70 MeV nucleon Fully quantum-mechanical
