  With the use of the symmetry-unrestricted cranked SHF method in the 3D
coordinate-mesh representation, a systematic search for the SD and HD
rotational bands in the N=Z nuclei from 32S to 48Cr has been done, and SD and
HD solutions have been found in 32S, 36Ar, 40Ca, 44Ti, and in 36Ar, 40Ca, 44Ti,
48Cr, respectively. The SD band in 40Ca is found to be extremely soft against
both the axially symmetric (Y30) and asymmetric (Y31) octupole deformations.
Possible presense of SD states in neutron-rich sulfur isotopes from 46S to 52S
has also been investigated, and deformation properties of neutron skins both in
the ground and SD states are discussed.
