THEORETICAL PREDICTIONS FOR THE SPECTRA. OF THE ODD-MASS XENON AND TELLURIUM ISOTOPES

The spectra of the isotopes Te/sup 123,125/, Xe/sup 127,129/ are calculated by assuming that the odd neutron, having available the 3s/sub 1/2/ and 2d/sub 3/2/ states, is coupled to collective surface vibrations of the core. Gocd agreement is obtained with the known levels in these nuclei using a reasonable value for the coupling parameter. To obtain the agreement, the d/sub 1/2/ -s/sub 1/2/ splitting, , must be regarded as a function of neutron number. The manner in which varies, as found in the intermediate coupling calculation is compared with the predictions of the pairing correlation theory originally introduced in connection with superconductivity. Agreement as to the general trend is found. This may be regarded to some extent as an indication of the applicability of the pairing correlation theory to nuclear structure calculations. (auth)
