摘要: Abstract An investigation of the properties Cd and Te isotopes is performed in framework interacting boson approximation. Particular attention paid to presence “intruder” 0 + 2 states at energy two-phonon triplet middle-shell isotopes. It suggested that these originate from two-particle two-hole proton excitations across shell gap Z = 50. The behaviour studied as a function neutron number. No clear evidence similar phenomena observed collectives features nuclei are found be satisfactory agreement with predictions neutron-proton model.
