    "abstract": "The bosonic strictly isospectral problem for Demkov-Ostrovsky (DO) effective\npotentials in the radially nodeless sector is first solved in the\nsupersymmetric Darboux-Witten (DW) half line (or l-changing) procedure. As an\napplication, for the \\kappa =1 class, if one goes back to optics examples, it\nmight be possible to think of a one-parameter family of Maxwell lenses having\nthe same optical scattering properties in the nodeless radial sector. Although\nthe relative changes in the index of refraction that one may introduce in this\nway are at the level of several percents, at most, for all DO orbital quantum\nnumbers l\\geq 0, the index profiles are different from the original Maxwell\none, possessing an inflection point within the lens. I pass then to the DW full\nline (or N-changing) procedure, obtaining the corresponding Morse-type problem\nfor which the supersymmetric results are well established, and finally come\nback to the half line with well-defined results",
