What is A Double Ionization Chamber for the Differential Method about?

A double ionization chamber for the differential method has been constructed, by which a minute difference in intensities (1 part in 105) of two 7-ray sources can be measured with the aid of a conventional sampling method. By the use of this chamber, the effect of superconductivity on the nuclear decay rate i of 99haTc has been measured, but no effect was found within an experimental error A2/1=(O.2+\_\_O.5)xlO -4. This result is consistent with our previous result, but is in essential disagreement with that of Byers and Stump. Another application of the device for determination of a long half-life is also demonstrated. The half-life of 6°Co was determined in a 10 d measurement as T! =(5.27+\_0.07)y, which is in excellent agreement with the current value.
