Random Probability Analysis of $^{48}$Ca$+^{239}$Pu Experimental Data

ORAL

Abstract

Element 114 (Fl), was discovered at the Flerov Laboratory of Nuclear Reactions (FLNR) using the $^{48}$Ca $+ ^{244}$Pu reaction and the Dubna Gas-Filled Recoil Separator (DGFRS) [1]. The structural properties of the super heavy elements are still largely unknown. The extent of the region of enhanced stability near Z$=$114 and N$=$184 is not completely known. To examine these properties, a new experimental data set has been taken using the $^{48}$Ca $+ ^{239}$Pu reaction at the DGFRS, in an effort to look for lighter isotopes of Fl. Progress on the production of lighter isotopes of Fl, cross-section measurements, and any nuclear decay properties will be discussed. Comparisons with reactions using heavier $^{242,244}$Pu targets and Monte Carlo random probability analysis will be highlighted[2]. \\[4pt] [1] Yu.Ts.~Oganessian, \textit{et al}., Phys. Rev.
