Several new alpha-emitting isotopes of francium were produced by the reactions Au/sup 197/(O/sup 16/,xn)Fr/sup 213-x, Tl/sup 203/(C/s up 12/,xn/) x Fr/ sup 215-x, Tl/sup 205/(C/sup 12,xn)Fr/sup 217-x, and Pb/sup 208(B/sup 11,xn)F r/ sup 219-x/. The nuclide studies lie on or below the 126-neutron closed shell. Their alpha-decay properties are as follows: Alpha-decay reduced widths delta / sup 2/ were calculated by using beta-decay systematics from this region to estimate the beta branching ratios. These reduced widths are compared to those of the isotonic polonium isotopes. (auth)
