“…CRC cal-culations have been performed to understand the mechanism of 1p and 2p stripping. Transfer of a proton from 16 O to the 2d 5 2 excited state of 143 Pr, while 15 N is left in the g.s., largely contributes to 1p-stripping cross sections. At higher excitation energies, contribution from the 1p 3 2 hole state of 15 N is found to be significant.…”

“…Spectroscopic factors for the 1p 1 2 ground state (g.s.) and 1p 3 2 third excited state of 15 N have been taken to be 1.275 and 2.047, respectively [42]. Spectroscopic factors for the overlaps between states in the target-like nuclei have been taken to be 1.0.…”

“…Magnetic spectrographs of varied configurations [9] had also been used to detect the scattered projectile-like ions from MNT reactions. In the last two decades, a new class of magnetic separators [10][11][12] with large acceptance, has been put to use in the study of MNT reactions [13][14][15]. Production of neutron-rich nuclides in damped collisions has been studied recently with novel applications of a few recoil separators which were not originally designed and built for this purpose [16][17][18].…”

We report the first direct measurement of differential transfer cross sections using a Recoil Mass Spectrometer. Absolute differential 1p and 2p-stripping cross sections at θ c.m. = 180 • have been determined for the system 16 O+ 142 Ce by detecting the heavier target-like ions at the focal plane of the Heavy Ion Reaction Analyzer. Focal plane spectra have been compared with the results of a semi-microscopic Monte-Carlo simulation to unambiguously identify the transfer channels. Transmission efficiency of the target-like ions through the spectrometer has also been estimated using the simulation which has been crucial to extract the cross sections from the yields of ions measured during the experiment. The methodology adopted in this work can be applied to measure multi-nucleon transfer cross sections using other similar recoil separators. The experimental excitation functions for the reactions 142 Ce( 16O, 15 N) 143 Pr and 142 Ce( 16 O, 14 C) 144 Nd have been compared with coupled reaction channel calculations. An excellent matching between measurement and theory has been obtained. For 1p-stripping, major contribution to the cross section has been found to be the transfer of a proton from 16 O to the 2d 5 2 excited state of 143 Pr, leaving behind 15 N in the 1p 1 2 ground state. Transfer of a cluster of two protons from 16 O to the 2 + excited state of 144 Nd, resulting in 14 C in the 0 + ground state, appears to be the most probable cause for 2p-stripping. Measured transfer probabilities for 1p and 2p channels have been compared with Time-Dependent Hartree-Fock calculations. Proton stripping channels are found to be more favourable compared to neutron pick-up channels. However, the theory overpredicts the measurement hinting at the need for extended approaches with explicit treatment of pairing correlations in the calculations.

We present new results on multi-nucleon transfer reactions in low-energy collisions of $$^{48}\hbox {Ca}+{}^{238}\hbox {U}$$ 48 Ca + 238 U measured at the velocity filter SHIP of GSI Helmholtz Centre, where we observed around 90 different nuclides from Tl to Am ($$Z=$$ Z = 81–95). We followed the idea to use uranium targets for the synthesis of neutron-rich MNT products, particularly in the region below lead, which was triggered by model calculations. The $$\gamma $$ γ , $$\alpha $$ α and spontaneous fission activities of the populated nuclides have been analyzed for their identification. The cross-sections of the observed isotopes for elements $$Z = $$ Z = 81–93 as a function of their mass number have been investigated. Excitation energy, total kinetic energy and the influence of nuclear shell effects on the production cross-sections of the observed transfer products have been studied. Also we present a compact review and comparative analysis of various multi-nucleon transfer and fragmentation reactions which are aimed at the synthesis of neutron-rich nuclides along the $$N=126$$ N = 126 shell closure in heavy nuclei.
