NUCLEAR REACTIONS ¹²²Sn(³⁵Cl, xn), E=156-174 MeV; measured γγ-coin, γ(θ), Eγ, Iγ. ¹⁵¹Ho deduced levels, J, π, γ-branching. A note was published in Ann.Phys.(Leipzig) 48, 611 (1991) by the Chief Editor of Annalen der Physik in regard to this article. A translation of the note follows: ' In the journal Ann.Phys.(Leipzig) Vol 46, No 8, P.561-568, 1989, there was an article by N.Mansour, T.Bayomy, Z.Awwad, A.Farhan entitled ' In Beam Gamma-Ray Studies of Band Structures in Ho¹⁵¹ ' which is in large part identical to the work published by J.Gizon, A.Gizon, S.Andre, J.Genevey, J.Jastrzebski, R.Kossakowski, M.Moszynski, Z.Preisbisz entitled ' High Spin Levels in ¹⁵¹Ho ' (Zeitschrift fur Physik 301 (1981) S.67-74). The work of N.Mansour et al cannot therefore be considered as original work any longer '. The article by J.Gizon et al., referred to has the key number 81Gi12 in the NSR file.
