Abstract: This paper comprises two separate parts. First, we present the high-spin states in <superscript>139</superscript>Pm nucleus. Two negative-parity dipole bands have been observed and assigned as πh<subscript>11/2</subscript>xν(h<subscript>11/2</subscript>)<superscript>-2</superscript> and πh<subscript>11/2</subscript>xν(h<subscript>11/2</subscript>)<superscript>-4</superscript> configurations. From the systematic comparison with neighboring nuclei and SPAC (Shears mechanism with Principal Axis Cranking) model calculations, the two bands can be suggested as magnetic rotational bands. In the other part of this paper, the construction of one new array of eight Clover and sixteen HPGe detectors has been introduced. The characteristics of the Clover detector have been presented and compared with Geant4 simulations. [ABSTRACT FROM AUTHOR]
