NUCLEAR SPECTROSCOPY ON Tl$sup 197$ SOURCES

Journal Article · · Arkiv Fysik
OSTI ID:4838362

The eonversion electron spectrum of mass-separated Tl/sup 197/ was studied at 5 to 2000 kev in a double focusing BETA spectrometer, adjusted to a momentum resolution of about 0.5%. Energy sum and intensity relations between the gamma transitions indicate the following level sequence in /sub 80/Hg/sup 19 / 7>s: ground state (1/2--), 133-95 (5/2--), 152-15 (3/2--), 308-5 (3/2--), partially checked by measurements of e-- gamma coincidences. The half life of Tl/sup 197/ was found to be 2.84 plus or minus 0.04 h. Conversion electron lines in the decay of the daughter nucleus Hg/sup 197/(65 h) were studied to some extent. (auth)
