With the advancement of the detector systems for γ-ray radiation, simultaneous measurement of time correlated photoelectric and Compton events recorded by employing segmented HPGe detectors (Clover Detectors) with very high energy resolution and efficiency, allows measuring the polarization of the γ-ray radiation in addition to the energy of the γ-ray radiation. The polarization measurement of the γ-ray radiation provides information regarding its electric or magnetic nature, which is essential for determining the parity of the decaying nuclear state. Data is shown for the low laying  states of

and polarization measurements. These measurements were carried out with the help of Indian National Gamma Array (INGA), New Delhi setup.
