Nuclear structure and decay of isomer in $$^{253}$$No were investigated. The isotope was produced by the reaction $$^{48}$$Ca+$$^{207}$$Pb. The excitation energy of the known single-particle isomeric state (5/2$$^{+}$$[622]) was measured by delayed coincidence between $$gamma$$-rays and implanted evaporation residues and was placed into the level scheme. In addition, decay of a high-lying multi-quasiparticle isomer in $$^{253}$$No was studied using e$$^{-}$$-$$gamma$$ coincidence measurements. A rotational band populated by its de-excitation was identified in $$^{253}$$No. A new isomeric state in $$^{253}$$Fm was observed and a partial-level scheme for this isotope is suggested. In addition $$gamma$$ transitions from excited levels are reproduced for $$^{253}$$Md.
