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