Simulation of angular and energy distributions for heavy evaporation residues using statistical model approximations and TRIM code

Charge distributions of Ra recoil ions produced in C12+Pb fusion-evaporation reactions

“…4 correspond to the most probable values Q + m = 8 for the equilibrated charges and Q + m = 19 for the nonequilibrated ones. The equilibrated value is close to the one adjusted with the MC simulation, whereas the most probable nonequilibrated value is between the two obtained in the same simulation (17 and 26) [28]. Using Eq.…”

“…The use of the sequential computation of the velocity vectors of heavy nuclei produced at each evaporation step allows us to take into account charged particle emission (protons and alphas) taking place at the CN deexcitation along with the emission of neutrons. This approach extended the description of the energy and angular distributions, which was earlier applied to the reactions with neutrons evaporation only [28]. As one could expect, simulations based on this extended approach were in good agreement with the measured ER angular distributions considered earlier [28].…”

“…4(a) we show the example of the similar decomposition using the two-component log-normal function fit to the transmission curve obtained for 210 Tables I and III [28] were used for a better description of the two-humped transmission curve obtained in the experiment [24].…”

“…The given error bars include statistical uncertainties [25] at the 68% confidence level as well as systematic uncertainties in the beam dose (±7%), DGFRS's transmission, and registration efficiency of decay chains (>90%). For the effective target thickness in all experiments, we used the value of 0.4 mg/cm 2 for Pu assuming that the first part of the thick target just reduces the beam energy and the ERs produced in this layer would not be able to reach the detectors [27].…”
