The multiconfiguration Dirac-Fock (MCDF) method was used to calculate the excitation energies of the levels of {sup 3}P and {sup 1}P in the lowest excited configurations for the two homolog elements of No I and Yb I. Also the transition probability of the 7s7p {sup 1}P{sub 1}{yields}7s{sup 2} {sup 1}S{sub 0} transition and the ground-state ionization energy of No I were calculated. The results for Yb I agree very well with the available experiments, with deviations of below 0.6% for the triplets and below 4% for the singlet. The result for the No I excitation energies clears the situation of conflicting results between Borschevsky et al., 30 056 cm{sup -1} (3.726 eV) [Phys. Rev. A 75, 042514 (2007)], and Fritzsche, 3.36 eV [Eur. Phys. J. D 33, 15 (2005)] for the 7s7p {sup 1}P{sub 1} level, which is planned to be measured in the near future with a newly developed experimental technique by Backe et al. [Eur. Phys. J. D 45, 99 (2007)]. The ionization energy result obtained in this work, 53 701 cm{sup -1}, is in excellent agreement with the scaled result of 53 600(600) cm{sup -1}.
