β-γ-γ directional correlation studies for the cascades (i)β-rays ofEmax=0.12 MeV,γ-rays of 557 keV andγ-rays of 53 keV and (ii)β-rays ofEmax=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 ofEmax 0.12 MeV→557→53 keV cascade andW(θ)=1+(0.163±0.042)P2(cosθ)+(−0.035±0.058)P4(cosθ) forβ rays ofEmax=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.
