LIFETIME OF THE 103 KEV LEVEL IN 93NP237,
Abstract
The half-life of the 103 keV level in 93Np237 has been found to be (8=4) X 10 to the -11th power sec. The experimental method utilizes the Doppler shift of 26 keV conversion electrons emitted from the 103 keV level following alpha decay of Am241. These electrons are examined in a high resolving power beta-ray spectrometer. The distribution of electrons is compared with the distribution obtained when the conversion electrons are successively decelerated and accelerated by an electrostatic field near the source. A finite lifetime results in a net acceleration of the conversion electrons. A method of analysis has been developed which enables the lifetime to be measured in terms of the resulting distortion of the original distribution. (Author)
