The conversion spectrum of the long-lived lutetium isotopes Lu/sup 173/ and Lu/sup 174/ is investigated. The relative conversion line intensity in the soft region of the spectrum (up to 250 kev) is measured in the Lu/sup 173/ spectrum. The per cent ratio of the Ml + E2 mixture for 78.6 and 100.6 kev transitions is determined. Conversion lines were detected in the lutetium-174 spectrum which can be ascribed to transitions connected with the isomer state of Lu/sup 174/ (E/sub gamma /= 44.7 kev Ml transition and E/sub gamma / = 59.0 kev M3 transition). The half life of the isomer state is approximately 90 days. (auth)
