Problem
A different odd-mass actinide nuclide decays by α emission to two levels of its daughter. Branch C, favoured because it preserves the odd nucleon's orbital, has intensity IC=90% and computed penetrability PC. Branch D, which requires a change of orbital, has intensity ID=0.060% and computed penetrability PD=2.5PC. Assume equal preformation factors for the two branches in the absence of any change of configuration. Find the hindrance factor of branch D relative to the systematics set by branch C.
