TL;DR: Here it is found experimentally that the lowest three states in the energy spectrum of the neutron deficient nucleus 186Pb are spherical, oblate and prolate, which is an apparently unique shape triplet.
Journal ArticleDOI

Robert Page,Andrei Andreyev,D. E. Appelbe,P. A. Butler,S. J. Freeman,Paul Greenlees,R-D Herzberg,D. G. Jenkins,G. D. Jones,P.M. Jones,D. T. Joss,Rauno Julin,Heikki Kettunen,M. Leino,Panu Rahkila,P. H. Regan,J. Simpson,Juha Uusitalo,SM Vincent,R. Wadsworth +19 more
TL;DR: The GREAT spectrometer as mentioned in this paper is designed to measure the decay properties of reaction products transported to the focal plane of a recoil separator, which can either be employed as a sensitive stand-alone device for decay measurements at the focal planes, or used to provide a selective tag for prompt conversion electrons or γ rays measured with arrays of detectors deployed at the target position.
Journal ArticleDOI
The Importance of Xylan for the Strength Properties of Spruce Kraft Pulp Fibres
TL;DR: In this article, the role of xylan in spruce kraft pulp fibres was investigated by selectively removing the pulp fibre xylan and also by sorbing xylan onto the pulp fibers.

TL;DR: In this paper, a Ge detector array, consisting of four clover detectors, and a gas-filled separator, was used to detect the ground state band of the Z = 102 nuclide 254No.
