Nuclear structure studies performed using the (18O,16O) two-neutron transfer reactions

“…Exact finite range coupled reaction channel (CRC) and two-step distorted wave Born approximation (DWBA) calculations for two-neutron transfer reactions were performed to describe the cross section, using the FRESCO code [29], with the same ingredients of ref. [17]. A direct, simultaneous transfer of the two particles was considered.…”

“…In this context, a wide range of systems were explored by heavy-ion induced one-and two-neutron transfer reactions at INFN-LNS (Italy) by the ( 18 O, 17 O) and ( 18 O, 16 O) reactions. The MAGNEX spectrometer [6] was used to detect the ejectiles.…”

“…In ref. [17] the experimental absolute cross sections of the one-and two-neutron transfer reactions induced by an 18 O beam on a 12 C target were reproduced without any scaling factor by means of Exact Finite Range (EFR) CRC calculations. Two approaches were used: the extreme cluster model and the independent coordinate scheme.…”

Measuring nuclear reaction cross sections to extract information on neutrinoless double beta decay

“…In a pioneering experiment, performed at the INFN-LNS laboratory, we studied the DCE reaction 40 Ca( 18 O, 18 Ne) 40 Ar at 270 MeV, with the aim to measure the cross section at zero degrees [5]. In the experiment an advantageous condition was set, using a beam of 18 O and a double magic target as 40 Ca and choosing the bombarding energy to mismatch the competing transfer reactions leading to the same outgoing channel.…”

The key tools in the experiment were the high resolution Superconducting Cyclotron beams and the MAGNEX spectrometer [7][8][9], a modern high resolution and large acceptance magnetic system [10][11][12][13] characterized by high resolution in energy, mass and angle.…”
