Alpha-decay properties of /sup 205-208/Fr: Identification of /sup 206/Fr/sup m/
Journal Article

· Phys. Rev., C; (United States)
Alpha-particle and ..gamma..-ray spectral measurements were made for /sup 205-208/Fr. A new a emitter (T/sub 1/2/ = 0.7 +- 0.1 sec and E/sub a/ = 6.930 +- 0.005 MeV) was observed and identified with the decay of a previously unknown isomer in /sup 206/Fr. From the a particle and g ray intensities, a decay branching ratios were deduced for /sup 205-208/Fr utilizing available information concerning the nuclides' (electron capture+positron) decay properties. Reduced widths were calculated and compared with those of neighboring nuclei.
