Clover detector has been used as a Compton polarimeter to measure the linea
r polarization of gamma-rays produced in heavy ion fusion reaction. The pol
arization sensitivity of the clover detector has been measured over gamma-r
ay energies ranging from 386 to 1368 keV. The E1 multipolarity of the 1117
keV transition in Rh-99 has been established using this polarimeter. This h
as resulted in the assignment of negative parity to the band head at 3710 k
eV in Rh-99.
