Title: Investigation of the effect of electric fields on the rate of alpha decay

Abstract

Possible alteration of the alpha decay rate of a {sup 249}Cf sample by application of an electric field of the order 10{sup 7} V/m was investigated. Gamma spectroscopy of the 388 keV level in the {sup 245}Cm daughter was used to eliminate the uncertainty inherent in absolute alpha counting. Ratios of the intensities of the 388 keV photopeak of {sup 249}Cf to photopeaks from both beta and electron-capture decay of {sup 152}Eu incorporated in the same sample were measured to eliminate variability due to changes in either sample geometry, or possible physical erosion of the samples. No change in any of the decay rates was seen within the estimated limits of reproducibility of the measurements. 16 refs., 5 tabs., 1 fig.
