beta. /sup +//electron-capture decay of /sup 192,194,196,198,200/Bi: Experimental evidence for low lying 0/sup +/ states
Levels in the /sup 192, 194, 196, 198, 200/Pb isotopes were studied via the ..beta../sup +//electron-capture decay of mass separated Bi isotopes. Multiscaled spectra of ..gamma.. rays, x rays, and conversion electrons, and ..gamma..-..gamma.. and ..gamma..-e/sup -/ coincidences were measured. The existence of 0/sup +/ states in the /sup 192-200/Pb nuclei is shown and evidence for the beginning of a collective band built on top of the 0/sub 2//sup +/ states is seen in /sup 192, 194, 196/Pb. A discussion in terms of characteristic properties of intruder states in the even-even nuclei and in terms of a one-broken-neutron-pair formalism is given. This shows clearly the presence of both neutron and proton (..pi..(2p-2h)) based states in the semimagic Pb nuclei at low excitation energy.
