TITLE=/DIRECT NEUTRON DECAY OF THE GIANT QUADRUPOLE RESONANCE IN 92ZR
AND ITS PARTICLE-HOLE STRUCTURE/;
PURPOSE=/THE 92ZR(4HE,4HE,N)91ZR REACTION THROUGH THE GIANT QUADRUPOLE
RESONANCE IN 92ZR WAS STUDIED WITH 4HE-N CORRELATION
MEASUREMENTS THREE GROUPS OF FAST NEUTRONS DECAYING FROM THE
GIANT QUADRUPOLE RESONANCE WERE FOUND, WHICH LEAVE
SINGLE-NEUTRON-HOLE STATES OF (!) (2D5/2)(-1), (!!)(1G9/2)(-1)
, AND (!!!)(2P)(-1) AND (1G)(-1) IN THE RESIDUAL 91ZR NUCLEUS.
THEY INDICATE THE MICROSCOPIC PARTICLE-HOLE CONFIGURATION OF
THE GIANT QUADRUPOLE RESONANCE. THE DIRECT FAST DECAY BRANCH
IS ABOUT 16%./;
