Empirical Rule For The Pair Break Mechanism In Three-Quasiparticle Rotational Bands, Sukhjeet Singh Dhindsa, Sushil Kumar, Jatinder Kumar Sharma

Turkish Journal of Physics

An empirical rule on the basis of odd-even mass difference is suggested for the breaking of a proton pair or a neutron pair in odd-A nuclei to form a lower lying 3-quasiparticle state. If \Delta_p is smaller than \Delta_n, the proton pair breaks; on the other hand, if \Delta_n is smaller than \Delta_p, the neutron pair breaks down and forms a lower lying 3-quasiparticle state in an odd-A nuclide. This rule appears not only purely based on the proton paring/neutron pairing energy balancing condition but also on particular excitation energy, which is \ge 1 MeV in the case of the …
