Our analysis of two‐quasi‐particle rotational bands in even‐even nuclei reveals an odd‐even staggering in both K+=‖&OHgr;1+&OHgr;2‖ and K−=‖&OHgr;1−&OHgr;2‖ bands. The phase of odd‐even staggering in K+and K−bands is found to be opposite which is in contrast to the behavior of these bands in odd‐odd nuclei. In the present paper, we report the preliminary results of our analysis to understand the behavior of these bands.
