Study of the multi-nucleon transfer reactions of¹³⁶Xe +¹⁹⁸Pt for producing exotic heavy nuclei

Abstract

Abstract. The feasibility of the multi-nucleon transfer (MNT) reaction in the 136 Xe + 198 Pt system was investigated for synthesizing neutron-rich heavy nuclei around mass number A∼200 of astrophysical interest. Identification of the projectile-like fragments (PLF's) was successfully performed by using VAMOS++ spectrometer. The isotopic distributions of the PLF's produced by two-proton stripping and pickup reactions were compared with each other, demonstrating the properties of the MNT reactions observed in the present system. The two-proton pickup channels strongly populated than the twoproton stripping channels were observed. The isotopic distributions for different total kinetic energy loss (TKEL) ranges are also discussed. The overall enhancement of the strength of the two-proton pickup compared with the two-proton stripping appears to be related to the MNT reactions with relatively moderate energy dissipation.

Deep-inelastic multinucleon transfer processes in the O16+Al27 reaction

“…3. The TKEL are derived assuming a pure binary process [52][53][54][55]. For the transfer reactions, as the number of transferred nucleons increases, there is a gradual shift of the centroid of energy-loss spectra toward the larger TKEL and reaches to as large as ∼ 70 MeV for the 27 Al( 16 O, 6 Li) channel.…”

Pathway for the Production of Neutron-Rich Isotopes around theN=126Shell Closure

“…The EXOGAM array [19] with ten CLOVER germanium detectors, surrounding the target, was used to detect γ rays from the PLFs and TLFs. The experimental setup and preliminary results of this measurement can be found in conference proceedings [20,21]. Obtaining absolute cross sections for isotopically identified fragments from a large acceptance spectrometer is demanding and there have not been too many such studies reported.…”
