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)P₂(cosθ)+(0.004±0.035)P₄(cosθ) forβ-rays ofE_max 0.12 MeV→557→53 keV cascade andW(θ)=1+(0.163±0.042)P₂(cosθ)+(−0.035±0.058)P₄(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.
