A variational procedure shows that two new types of spin density wave (SDW)ground states appear successively in the fitted system modeling the Bechgaardsalts, when the transverse transfer energy increases around its upper bound im-posed for the usual SDW state having the so far known best nesting wave vector.From this value the wave vectors of the new states are appreciably shifted, entail-ing uncompensated carrier pockets of the size found in the Shubnikov-de Haasexperiments. An analytic expression clarifying the situation of the starting-pointof the shift shows that the shift is sensitive to details of the system.
