Abstract
Alpha decay from Ra-225 has been observed for the first time. 5006 +/- 5 ke V and 4976 +/- 5 keV alphas with intensities 2.0 +/- 0.5 x 10(-5) and 6 +/- 3 x 10(-6) and alpha decay hindrance factors 40 +/- 10 and 70 +/- 35, resp ectively, are reported. The corresponding levels in Rn-221 are the ground s tate (7/2(+)) and 30 +/- 10 keV excited state (tentatively 3/2(+)) with the octupole deformed configurations 3/2(-0.1 0.6) mixed with 1/2(-0.1 0.5 -2) .
