“…To establish the nuclear density distribution from the measured cross section, the Glauber multiplescattering theory was applied similarly as in Refs. [47,[49][50][51]. The differential cross sections for proton elastic scattering on composite targets were calculated as…”

Absolute differential cross sections for elastic p 7 Be and p 8 B small-angle scattering were measured in inverse kinematics at an energy of 0.7 GeV/u at GSI Darmstadt. The hydrogen-filled ionization chamber IKAR was used as an active target to detect the recoil protons. The projectile tracking and isotope identification were performed with multi-wire proportional chambers and scintillation detectors. The measured cross sections were analysed using the Glauber multiple-scattering theory. The root-mean-square (rms) nuclear matter radii R m = 2.42(4) fm for 7 Be and R m = 2.58(6) fm for 8 B were obtained. The radial density distribution deduced for 8 B exhibits a proton halo structure with the rms halo radius R h = 4.24(25) fm. A comparison of the deduced experimental radii is displayed with existing experimental and theoretical data.

We have proposed a procedure to extract the probability for valence particle being out of the binding potential from the measured nuclear asymptotic normalization coefficients. With this procedure, available data regarding the nuclear halo candidates are systematically analyzed and a number of halo nuclei are comfirmed. Based on these results we have got a much relaxed condition for nuclear halo occurrence. Furthermore, we have presented the scaling laws for the dimensionless quantity < r 2 > /R 2 of nuclear halo in terms of the analytical expressions of the expectation value for the operator r 2 in a finite square-well potential.

“…The study of neutron-rich drip line nuclei and neutron (proton) halo is one of most prominent branches of modern nuclear physics [1,2]. A variety of advanced techniques have been introduced to study the structural properties of neutron and proton halo nuclei [3][4][5][6][7][8]. The separation energy of the outer nucleon(s) in nuclei near the drip line becomes extremely small.…”

“…The neutron-rich nuclei 6,8 He, 11,14 Be and 11 Li are the best investigated and established neutron-halo nuclei. Abdullah [12] has been used the three body model of (Core +2n) within the radial wave functions of Woods-Saxon (WS) potential to investigate the ground state densities, the corresponding rms radii and elastic form factors of neutron-rich 6 He, 11 Li, 12 Be and 14 Be halo nuclei. The obtained results were discussed and compared with the experimental one.…”

Abdullah [13] has been investigate the ground state properties such as, the binding energy per nucleon, the ground state densities and the corresponding rms radii of two-neutron 6 He, 11 Li, 12 Be and 14 Be halo nuclei by means of the Skyrme-Hartree-Fock (SHF) method with MSK7 Skyrme parameter.…”

We have calculated some of the basic structural properties such as the ground state proton, neutron and matter densities and elastic form factors of halo nuclei namely, 11 Be and 14 Be using the binary cluster model (BCM) within the Gaussian and harmonic oscillator wave functions. The halo nuclei have been considered as a compact core with loosely bound valence neutron(s) forming the halo. The comparison between the calculated and experimental matter density distributions supports the halo structure for 11 Be [ 14 Be] where the valence one neutron [two neutrons] occupy the 1p1/2 [(2s1/2) 2 ] orbital. We have also calculated the reaction cross sections () for these nuclei using the Glauber model with an optical limit approximation at low and high energies. The calculated () of these nuclei give a good description of experimental data at both low and high energies.
