Structural properties and α-decay chains of transfermium nuclei (101≤Z≤110)

Transfermium nuclei (101≤Z≤110) are investigated thoroughly to describe structural properties viz. deformation, radii, shapes, magicity, etc. as well their probable decay chains. These explored using relativistic mean-field (RMF) approach and compared with other theories along available experimental data. Neutron numbers N=152 162 have come forth a deformed shell gap whereas N=184 is ensured spherical magic number. The region N>168 bears witness of the phenomenon shape transition coexistence for all considered isotopic Experimental α-decay half-lives our theoretical obtained by various empirical/semi-empirical formulas. recent formula proposed Manjunatha et al., which results best among 10 formulas, further modified adding asymmetry dependent terms (I I2). This utilized predict chains that found in excellent agreement
