Abstract：

Assuming a core plus valence nucleon structure, one-nucleon removal reaction
is investigated within the framework of few-body Glauber theory. Fermi-type distribution is used for the core density, while the wavefunction of the valence nucleon is calculated by solving the single particle eigenvalue problem of the Schrödinger equation with the Woods-Saxon potential. The parallel momentum distribution (P_//) of the fragments is calculated for isotopes with 3 R ² _v/ R ² _con the full width at half maximum of the parallel momentum distribution (FWHM _P//). R ² _v/ R ² _cis a measure of the exotic extent of the nuclear halo. Based on the obtained scaling law, FWHM _P//can be used as an experimental observable to extract R ² _v/ R ² _cand measure the exotic extent for the nuclear halo.
