/* IN THIS PAPER WE PROPOSE A NEW METHOD FOR MAGNETIC MOMENT
MEASUREMENT OF A SHORT-LIVED LEVEL POPULATED BY A NUCLEAR REACTION.
THIS METHOD IS ESSENTIALLY THE MODIFICATION OF A TIME INTEGRAL
PERTURBED ANGULAR DISTRIBUTION OF EMITTED GAMMA-VAYS.
PRELIMINARY RESULTS OF THIS STUDY WAS ALREADY REPORTED IN SHORT
