β-γ-γ directional correlation studies for the cascades (i)β-rays ofE max=0.12 MeV,γ-rays of 557 keV andγ-rays of 53 keV and (ii)β-rays ofE max=0.21 MeV,γ-rays of 444 keV andγ-rays of 53 keV have been made. The triple correlation functionsW(θ) were obtained to beW(θ)=1+(−0.153±0.031)P 2(cosθ)+(0.004±0.035)P 4(cosθ) forβ-rays ofE max 0.12 MeV→557→53 keV cascade andW(θ)=1+(0.163±0.042)P 2(cosθ)+(−0.035±0.058)P 4(cosθ) forβ rays ofE max=0.21 MeV→444 keV→53 keV cascade. Spins and parities of the 650, 537 and 93 keV levels of103Rh are deduced by triple angular correlation and the internal conversion coefficient studies. Multipolarities of the transitions are also determined
