Experimental investigation of the count-loss effect due to the time interval between counting-gates in the Feynman- method

Yamane and Hayashi derived a new formula for the variance-tomean ratio that takes the channel advance time of a multi-channel scaler into account. If the channel advance time is much smaller than the channel width (as in practice), then its effect can be numerically shown to be negligible. It might be for this reason that experimental results that validate the new formula have never been published. However, by introducing an artificial long channel advance time equal to the width of one channel, the effect becomes significant and can be demonstrated experimentally. With these experimental results, the new formula could be validated
