225TH cA E Measurements of 1961Ru06. Original energies have been
225TH2cA increased by 5 keV due to calibration, as recommended by 1979Ry03.
225TH cA IA |a intensity per 100 |a decays, measured by 1961Ru06.
225TH cA HF r{-0}({+225}Th)=1.53 is used in calculations.
225TH c No gammas were observed by 1961Ru06 in singles and |a|g-coincidence
225TH2c spectra (<2% of |a decays) belonging to {+229}U |a decay. However,
225TH3c Th L x rays were observed, and their intensity was measured as
225TH4c 13% of |a decays. These data indicate, as concluded by 1961Ru06, that
225TH5c the levels populated by the 6332- and 6297-keV |a's are deexcited
225TH6c by M1,E2 transitions, not by E1.
225TH L 0.0 (3/2+)

225TH cA IA uncertainty was recommended by 1979Ry03.
225TH cA The 6360-keV |a was not seen in coincidence with gammas,
225TH2cA indicating that it feeds either the g.s. or a low-energy level
225TH2cA deexcited by |g's with E|g less than
225TH3cA the Th L-electron binding energy.
