Two-particle transfer processes as a signature of shape phase transition in Zirconium isotopes

We explore two-particle transfer reactions as a crucial probe of the occurrence shape coexistence in phase transitions. The (t,p) to ground state and excited 0+ states are calculated for isotope chain even-even Zirconium isotopes starting from stable nuclei up beyond current experimental limits. Two-particle spectroscopic factors derived Monte Carlo Shell Model calculations used, together with sequential description reaction mechanism. calculation shows clear signature transition between 98Zr 100Zr, which displays deformed an spherical state. Furthermore, we show that there is qualitative difference respect case normal can be discriminated two-neutron reactions.
