Study of 10Li via the 9Li(2H, p) reaction at REX-ISOLDE

Abstract

The 9 Li + 2 H reaction has been investigated at 2.36 MeV/u at the REX-ISOLDE facility. In this Letter we focus on the 10 Li + p channel which potentially holds spectroscopic information on the unbound nucleus 10 Li. The experimental excitation energy spectrum and angular distribution are compared with CCBA calculations. These calculations clearly support the existence of a low-lying (s) virtual state, with a (negative) scattering length of the order a s ∼ 13-24 fm and a p 1/2 resonance with an energy of E r 0.38 MeV and a width of Γ 0.2 MeV.

Theory of (d,p) and (p,d) reactions including breakup: Comparison of methods

“…There have been a few applications of CDCC to transfer reactions (e.g., Refs. [5,[22][23][24][25][26]), and results demonstrate the variety of phenomena that can be addressed within this same framework. While new developments of the CDCC method are taking place [27][28][29], here we would like to focus on a better understanding of the transfer matrix element when breakup is included.…”

“…Reactions on light targets, such as (d,p), are of particular experimental interest because the Coulomb barrier is minimized. Recent measurements have mostly focused on light nuclei [2][3][4][5][6], but interest in the heavier isotopes is increasing [7,8].…”

Three-body properties of low-lying12Be resonances

“…However, a number of low-lying many-body resonances in light nuclei can still be well described as cluster structures even when they appear in the continuum. Prominent examples are found in stable nuclei such as 12 C and 9 Be [5][6][7][8][9][10][11][12][13], but even ground states like in 6 Be [14][15][16][17] and 10 Li [18][19][20] may appear as resonances.…”

Halo nuclei, stepping stones across the drip-lines

“…The momentum vectors are used for an expansion into HH for the three-body system. Spectroscopy of the recoiling 10 Li system [51,52] provides additional information on the subsystems interaction. Figure 6 presents the reconstructed width of the removed neutrons momentum distribution plotted versus the relative energy in the 10 Li intermediate system.…”
