High spin states in Re-174 are investigated via the Sm-152(Al-27, 5n gamma)Re-174 reaction and gamma-gamma coincidence relationships are analysed carefully. A new band is identified due to its spectroscopic connection with the known pi 1/2(-)[541] circle times nu 1/2(-)[521] band. This band is proposed to be the ground-state band built on the pi 1/2(-)[541] circle times nu 5/2(-)[512] configuration in view of the low-lying intrinsic states in the neighbouring odd-mass nuclei. It is of particular interesting that the new band exhibits a phenomenon of low-spin signature inversion, providing a new situation for theoretical investigations.

Brown sediment with two different domains; one coarse grained, and one finer grained. In the coarse grained domain, clasts range from small to large in size. The clast shape ranges from sub-angular to rounded. Rotation structures and edge-to-edge grain crushing is commonly seen. In the finer grained domain, clasts are mainly small, with a few larger clasts, and there is an abundance of lineations.
