Study of the reaction ⁷⁰Zn (15 MeV/nucleon) + ⁶⁴Ni with the MAGNEX spectrometer for the production of neutron-rich isotopes

Abstract

We describe our efforts to study the production of neutron-rich isotopes from peripheral reactions of medium-mass heavy ions with the MAGNEX spectrometer at the INFN-LNS in Catania, Italy. Experimental data were obtained for the 70Zn+64Ni reaction at 15 MeV/nucleon. For the analysis of the data, we developed a new procedure for the reconstruction of both the atomic number Z and the ionic charge q of the ions, which is then followed by the identification of the mass. Preliminary results and the analysis plan will be discussed.

Recent Progress in the Study of the Reaction 70Zn (15 MeV/nucleon) + 64Ni with the MAGNEX Spectrometer

“…We were in position to select events of specific Z and q after proper gating. An example of this approach can be found in [24,27,28].…”

Measurements of projectile fragments from 70 Zn (15 MeV/nucleon) + 64 Ni collisions with the MAGNEX spectrometer at INFN-LNS

“…In order to determine the velocity-dependent coefficients a0(υ), a1(υ) and a2(υ) in the velocity range of interest, we followed the scheme of Ref. [11,12] for Z range 6-36 and in the energy range of 8-18 MeV/nucleon via a least-squares fitting procedure at each energy in steps of 0.5 MeV/nucleon. The values of each coefficient at the various energies were afterwards fitted with polynomial functions of velocity.…”

Momentum Distribution Studies of Projectile Fragments from Peripheral Collisions Below the Fermi Energy

“…Apart from fragmentation [8] and spallation [9], multinucleon transfer reactions offer the means to produce these nuclei. Our group specifically focuses on the study of these reactions in the Fermi energy regime MeV/nucleon) [10][11][12][13][14][15][16][17][18]. In this work we present the study of a reaction with a 86 Kr beam at 15 MeV/nucleon with a target of 64 Ni.…”
