“…In the analysis, the branching ratio of the decay was used as 0.95 ( 250 Fm), 0.15 ( 249 Fm), and 0.99 ( 248 Fm) [18]. Our data are close to those of [14] in the absolute values and the E c:m: values corresponding to the maximum cross sections for each xn channels. The 4n-channel cross section in Ref.…”

Evaporation residue cross sections in the 16O+238U reaction were measured for the energy range from above- to extreme sub-barrier. The cross sections are reproduced by a statistical model calculation, for which partial cross sections are calculated by a coupled-channel model taking into account the prolate deformation of 238U. Complete fusion was observed in the collision of the projectile with the tips of the 238U target, in the same way as the side collision.

“…For the 16 [14], whereas the data in [15] gives the maximum at 86 MeV and the cross section drops below this energy. The different conclusions are derived in the sub-barrier region, necessitating further measurement.…”

“…Helium was superior to argon as the stopping medium but argon was employed occasionally (67) . An admixture of 1 per cent air to the helium reduced the collection efficiency of rare earths by a factor of two (50) but increased that of astatine by an order of magnitude (68 example, sequential counting of the activity with several solid-state detec tors (69) , or operation inside a cyclotron chamber (70,71). Construction details may be seen in these and other publications (72-74).…”
