Nuclear spectroscopic information for known nuclides of mass number 151 (Cs,Ba,La,Ce,Pr,Nd,Pm,Sm,Eu, Gd,Tb,Dy,Ho,Er,Tm,Yb,Lu) with Z = 55 to 71 and N = 96 to 80 have been evaluated and presented together with adopted energies and J{pi} of levels in these nuclei. No excited state data are yet available for {sup 151}Cs, {sup 151}Ba and {sup 151}La; only the isotopic identification has been reported, without information about their half-lives or decay modes. The {sup 151}Hf nuclide has not yet been identified. The radioactive decays of {sup 151}Ce, {sup 151}Ho (35.2-s and 47.2-s activities), {sup 151}Er (23.5-s and 0.58-s activities), {sup 151}Yb (two activities of about the same half-life) are not well established. For the decay of {sup 151}Lu, only the half-life is known. Superdeformed structures are well established in {sup 151}Dy and {sup 151}Tb with a total of five SD bands in {sup 151}Dy and ten SD bands in {sup 151}Tb. In {sup 151}Gd, six SD bands have been tentatively assigned. In {sup 151}Tb, yrast SD-1 band has now (2008Ro23) been linked to normal-deformed structures through two well-defined high-energy {gamma} transitions and possibly four other tentative {gamma} rays. This evaluation represents a revision of earlier (1997Si03,1988Si15,1976Ha35) evaluations of A = 151.
