A rotational band with five $$gamma$$-ray transitions ranging from 2$$^+$$ to 12$$^+$$ states was identified in $$^{40}$$Ar. The deduced transition quadrupole moment of 1.45 $$pm$$0.15 eb indicates that the band has a superdeformed shape. The nature of the band is revealed by cranked Hartee Fock Bogoliubov calculations and a multiparticle-multihole configuration is assigned to the band.

Modest spin states in neutron-rich $$^{187}$$W have been populated using a $$^{186}$$W($$^{18}$$O,$$^{17}$$O) one-neutron transfer reaction. While negative-parity bands previously known are extended to higher spin, two positive-parity bands are newly identified. Configurations based on $$nu$$ i$$_{13/2}$$ orbitals are assigned to these bands from an analysis of the level energy systematics as well as the g-factors derived from in-band branching ratios.

Excited states in neutron-rich $$^{188}$$W have been populated using a $$^{186}$$W($$^{18}$$O,$$^{16}$$O) reaction. In-beam $$gamma$$ rays were measured in coincidence with scattered particles detected by a high-resolution $$Delta E$$-$$E$$ Si telescope. In this experiment, the ground state band has been identified up to $$I^pi=8^+$$. The $$gamma$$ band, the $$K^pi=2^-$$ octupole band, and a 2-quasiparticle state were also observed. The results are compared with predictions of self-consistent HFB cranking calculations and blocked-BCS multi-quasiparticle calculations.

Neutron-rich W-Os nuclei with $$Aapprox190$$ exhibit the various signature of nuclear collective motions such as $$gamma$$-softness, triaxiality, and a prolate-oblate shape transition. In addition, the emergence of high-$$K$$ isomers, where $$K$$ is the angular momentum projection on the nuclear symmetry axis, based on multi-quasiparticle excitation is a characteristic of nuclei in this region. The recent experimental and theoretical studies of the neutron-rich W nuclei have revealed the existence of high-$$K$$ multi-quasiparticle isomers. Here we report results from the in-beam $$gamma$$-ray spectroscopic experiments on neutron-rich $$^{187}$$W and $$^{188}$$W.
