Description of long-lived isomers in ²⁵⁴₁₀₁Md₁₅₃

Spectroscopic data in respect of Trans-Fermium nuclei beyond the N=152 deformed shell closure are very rare, and rarer still is a credible interpretation of such data. Presently available experimental information on the lightest such nucleus provides a typical instance illustrating this feature. In particular, level structures of the isotonic ²⁵²Es and isotopic ²⁵⁰Md neighbours have been investigated earlier by us using this formalism
