Production of lanthanide molecular ion beams by fluorination technique

“…Figure 5 shows the yields measured for the most volatile Ln isotopes released without fluorination by UC x pellets heated at ∼ 2050 • C. The spectroscopic data required to extract the yields from the γ spectra, in particular the half-lives and the absolute γ intensities, were taken from refs. [16][17][18][19][20]. This result proves that the Ln photo-fission cross sections are sufficient to allow the observation of Ln mass-separated ion beams provided that the target temperature is high enough.…”

“…Moreover, the plot for the 238.6-keV band shows a backbending at similar rotational frequency hω ≈ 270 keV. It is then likely that the band on top of the 238.6-keV level corresponds to the 5/2 − [523] neutron configuration, seen also in the Sm,Gd,Dy and Er, N=91 isotones [22][23][24][25].…”

Decomposition studies of group 6 hexacarbonyl complexes. Part 1: Production and decomposition of Mo(CO)6 and W(CO)6

“…Two isotopes 163 W ( 1/2 = 2.6 s, = 5.384 MeV) [19] and 164 W ( 1/2 = 6 s, = 5.150 MeV) [20] were produced in the heavy-ion induced nuclear fusion reaction Here, the products passed through a thin Mylar window separating GARIS from the carrier gas of the chemistry setup. Subsequently, they were thermalized in the CO/He (50 : 50 vol-%) carrier gas flushing through the recoil transfer chamber (RTC).…”
