The level structure of Nd-147 has been studied from the decay of 147Pr. The radioactive sources of 147Pr were separated from the fission products of U-235 using the on-line isotope-separator KUR-ISOL and chemical separation techniques. A decay scheme has been constructed involving 93 gamma-rays and a newly observed 1261.1 keV level. The half-lives of 49.9, 127.8 and 214.6 keV levels were determined to be 1.0 +/- 0.3 ns, 0.4 +/- 0.1 ns and 4.53 +/- 0.06 ns, respectively. Conversion coefficients of 15 transitions were determined. The parities for the levels at 49.9, 127.8, 214.6, 314.7 and 463.5 keV are deduced to be odd. Spins and parities for the 769.3 and 792.6 keV levels are deduced to be 3/2+. The properties of transition probabilities between the low-lying triplet hole states are similar to that of three particle states in the N=85 isotones.
