THE BRANCHING RATIO OF THORIUM C

Journal Article · · Proc. Phys. Soc. (London)
The branching ratio of thorium C (Bi/sup 212/) was determined from the intensities of the two alpha particle groups. Sources of ThB were electrcdeposited from thoron on a polished brass surface, 1 mm in diameter, and were mounted 1 cm above an aperture of the same diameter in a mica disc covering the crystal. The branching ratio was found to be alpha /( alpha + BETA ) = 0.359 plus or minus 0.002. (J.R.D.)
