The yrast spectra with J{sub max}{sup {pi}}=10{sup +},B(E2) transition probabilities and Q{sub J{sup +}} values are calculated for even-even xenon isotopes by carrying out variation-after-projection calculations in conjunction with a Hartree-Fock-Bogoliubov (HFB) ansatz employing a pairing-plus-quadrupole-quadrupole effective interaction operating in a reasonably large valence space outside the {sup 100}Sn core. Our calculations reveal that the systematics of low-lying yrast states in these isotopes are intricately linked with the manner in which neutrons tend to occupy the various valence orbits. The results on B(E2) transition probabilities predict a dip in the isotopes {sup 114,116,120,124,128}Xe, which might be construed to imply different structures for {sup 114,116,120,124,128}Xe as compared to their neighbors. Besides this, our results also reveal that both the HFB technique and the quadrupole-quadrupole-plus-pairing model of the two-body interaction are fairly reliable in this mass region. {copyright} {ital 1997} {ital The American Physical Society}
