Decay of ^201-203Ra and ^200-202Fr

RADIOACTIVITY ^{200,201,201m,202,202m}Fr, ^{201,201m,202,203,203m}Ra(α)[from ^147,149Sm(⁵⁶Fe, X), E=236-275 MeV]; ^198,199,199mRn, ^196,197,197mAt, ^198,198mAt, ¹⁹⁴Po(α)[daughters of Fr and Ra α decay chains]; measured Eα, Iα, γα-coin, Eγ, Iγ, (evaporation residues)α and α₁-α₂, ER-fission correlations, half-lives using SHIP separator at GSI; deduced level energies of some of the isomers, Q(α), α branching ratios for some activities, reduced widths from Rasmussen prescription. ^200,201Fr; deduced new micro-sec isomers from γ-ray and x-ray data, half-lives. ²⁰⁰Fr; deduced evidence for beta-delayed fission from Er-fission correlated events. Comparison with previous experimental data. Systematics of Q(α) and reduced α widths in N=102-140 Po, Rn and Ra isotopes. Systematics of single-particle levels in N=104-126 Fr, At and Bi isotopes.
