Abstract
The high spin states of 143Gd have been studied via the
reaction at 170 MeV. One dipole cascade
has been newly found and two dipole cascades have been extended to higher
spin states. A relatively long E2 cascade consisting of irregular transition
energies has been found, which has only weak connections to the other dipole
and quadrupole cascades. This resembles the ones recently found in
142,143,144Eu and 144Gd. The dipole and quadrupole cascades have
been found to appear by turns in an energy increment of about 0.2MeV above
the yrast line.
