Abstract

Several new alpha-emitting isotopes of francium have been produced by the reactions

{Au}^{197} (O^{16}, x n) {Fr}^{213 - x}

,

{Tl}^{203} (C^{12}, x n) {Fr}^{215 - x}

,

{Tl}^{205} (C^{12}, x n) {Fr}^{217 - x}

, and

{Pb}^{208} (B^{11}, x n) {Fr}^{219 - x}

. The nuclides studies lie on or below the 126-neutron closed shell. Their alpha-decay properties are as follows:
