A simplified carbon reservoir model with lucid analytical solutions is presented. Analytical model solutions are obtained for situations with growing, constant, and decaying atmospheric emissions of carbon dioxide (CO2), scenarios which are of releva

The density of accessible levels at low spin in the ( ${}^{3}\mathrm{He},\ensuremath{\alpha}\ensuremath{\gamma}$) reaction has been extracted for the ${}^{162}\mathrm{Dy}$, ${}^{166}\mathrm{Er}$, and ${}^{172}\mathrm{Yb}$ nuclei. The nuclear temperat

Excited states in 171Ir have been observed for the first time. Gamma-rays were assigned to the nucleus by the recoil-decay tagging method. The ground-state band has a structure consistent with an h 11 2 proton coupled to a core of large triaxial defo

Rotational bands in the odd-proton nucleus 171 Lu have been populated with the 160 Gd( 19 F, α4n) reaction. High-spin states were observed to a maximum spin of 73 2 − using the NORD-BALL array. Several new three-quasiparticle bands were observed,

Six rotational bands in the odd-odd nucleus 174Ta have been populated with the 160Gd(19F,5n) reaction. High-spin states were identified using the NORDBALL array. Both signatures of the doubly decoupled π 1 2 − [541] ⊗ ν 1 2 − [521] band and s

A new method for unfolding γ-ray spectra is described. The method is based on the fact that the contribution of Compton scattered γ-rays in the spectra is a slowly varying function of energy. Thus, the Compton part can be smoothed and subtracted fr

An experimental investigation of the nucleus 165Lu, using the reactions 138Ba(31P,4n) 165Lu and 150Sm(19F,4n) 165Lu at beam energies of E = 155 and 95 MeV, respectively, has been performed. Among other additions to the existing level scheme, a new ba

High-spin properties of rotational bands are studied in 173Ta using the 160Gd(19F,6n) reaction at bombarding energies of 103–105 MeV. With the existing bands being extended, and new bands established, a total of 16 rotational sequences are interpre

The level scheme of 177Re has been extended extensively, with fragments of more than thirty bands, characterised by a given signature, observed. Alignments at low frequency in one-quasiparticle bands are interpreted as deformation effects and compare
