Shape transition and shape coexistence in odd-mass nuclei around <sup>100</sup>Zr Open
The A = 100 mass region is of special interest due to a rapid shape transition from nearly spherical to strongly deformed shapes by going from neutron number 58 to 60, especially pronounced in the Sr and Zr isotopes. The sudden change of t…
