Cross Sections of the Production of Mercury and Radon Isotopes in Complete Fusion Reactions with 36,40 Ar and 40,48 Ca Projectiles

A modified catcher foil technique is used to measure the absolute cross sections of xn -evaporation channels in complete fusion reactions 144 Sm( 40 Ar, xn ) 184− x Hg, 148 Sm( 36 Ar, xn ) 184− x Hg, 144 Nd( 40 Ca, xn ) 184− x Hg, 142 Nd( 48 Ca, xn ) 190− x Hg, and 166 Er( 40 Ar, xn ) 206− x Rn. The effect the spread of the beam’s energy has on the excitation functions as it moves through absorbing foils and the target is addressed by means of deconvolution. The measured excitation functions are compared to ones calculated theoretically using the coupled-channel model.
