Nuclear Molecule of Heavy Nuclei / T.M.Shneidman, R.G.Nazmitdinov. – Text : electronic // Journal of Physics A: Mathematical and Theoretical. – 2026. – Vol. 59, No. 21. – P. 215203. – URL: https://doi.org/10.1088/1751-8121/ae6adb.

A model for a nuclear molecule composed of two heavy nuclei is proposed. To this end, the Hamiltonian of the dinuclear system is derived and diagonalized within a basis of bipolar spherical harmonics. Approximate analytical expressions describing the excitations of highly deformed molecular states are obtained. A remarkable agreement between numerical and analytical results is demonstrated in the description of low-energy roto-vibrational excitations in *2*4*0Pu. Furthermore, we provide predictions for the spectrum of hyperdeformed states in *2*3*2Th, treating it as a nuclear molecule consisting of *1*3*2Sn and *1*0*0Zr fragments. Finally, the angular distribution of fission fragments for *2*4*0Pu is analyzed and found to be in good agreement with available experimental data.
