4 INDEPENDENT DECAY PROPERTIES IN THE SUPER-DEFORMED WELL OF EU-143

The flow of gamma-transitions through the superdeformed minimum of Eu- 143 is investigated by studying the intensities of four different type s of gamma-rays of superdeformed origin, obtained with a variety of ga ting conditions. They can all be explained rather well by schematic si mulation calculations assuming only well known statistical properties. Information on level density, competition between E1 and E2 strengths and rotational damping width in the SD well is obtained, yielding a r ather complete picture of the feeding mechanism into different regions of the second minimum.
