Symmetric collisions of massive nuclei, such as 238U + 248Cm, have been proposed ways to make new n-rich heavy nuclei via multi-nucleon transfer (MNT) reactions. We measured the yields several projectile-like and target-like fragments from reaction 1360 MeV 204Hg 198Pt. find that current models for this symmetric collision (GRAZING, DNS, ImQMD) significantly underestimate these products, even small transfers.
A previous study of symmetric collisions massive nuclei has shown that current models multinucleon transfer (MNT) reactions do not adequately describe the product yields. To gain further insight into this problem, we have measured yields MNT products in interaction 977 ($E/A=4.79$ MeV) and 1143 MeV ($E/A=5.60$ $^{204}\mathrm{Hg}$ with $^{208}\mathrm{Pb}$. We find yield are similar these two substantially lower than those observed reaction 1257 ($E/A=6.16$...
States in $^{209}\mathrm{Tl}$ were populated using a multinucleon transfer reaction with $^{136}\mathrm{Xe}$ beam impinging on thick $^{208}\mathrm{Pb}$ target at $E=785$ MeV. The was pulsed 825-ns intervals order to perform isomer decay spectroscopy. known ${J}^{\ensuremath{\pi}}=17/{2}^{+}$ located 1228(4) keV and measured have half-life of ${T}_{1/2}=146(10)$ ns. A second ${J}^{\ensuremath{\pi}}=13/{2}^{+}$ found ${T}_{1/2}=14(5)$ previously suggested low-energy X Y transitions energies...
This paper presents the establishment of neutron calibration laboratory for first time in Jordan based on a 252Cf source. The discusses scattering influence field terms international standards. It also represents laboratory's design, source shielding and implemented safety features. Data was acquired using two spherical devices same type placed at different sides laboratory. room's determined three methods: shadow cone, semi-empirical, reduced fitting. measurements were conducted distances...
