Decay of $sup 209$Rn. Excited states of $sup 209$At (in Russian)

Technical Report ·
OSTI ID:4938092
; ; ; ; ; ; ;
Radiation of /sup 209/Rm is studied. The decay scheme /sup 209/Rn yields / /sup 20 9/ At is suggested. Twenty-four excited states of /sup 209/At are introduced. The population parts of /sup 209/At excited states are determined for /sup 209/Rn decay. The corresponding values of lg ft are calculated. Two components of positrons at /sup 209/Rn decay are observed; the mass difference, /sup 209/Rn yields /sup 209/At, is determined: Q/sub BETA / = (3928 plus or minus 4 0) keV. Possible nature of /sup 209/At excited states is discussed. (auth)
