Rotational-invariant model of the states with K-pi=1(+) and their contribution to the scissors mode (WORLD SCIENTIFIC PUBL CO PTE LTD, 2000)Within the Random-Phase Approximation the method of self-consistent determination of the isoscalar and isovector effective separable interactions restoring a broken symmetry of the deformed mean-field is given. The method ...
