(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The natural log of experimental nuclear level densities at low energy is linear with energy. This can be interpreted in terms of a nearly 1st order phase transition from a superfluid to an ideal gas of quasi particles. The ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)We investigate the effect of waves on the airflow in horizontal two-phase pipe flow. Velocity fields in the gaseous phase were acquired by particle image velocimetry (PIV), while interfacial elevation was measured with ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)[1] Subcritical cracking behavior and surface energies are important factors in geological processes, as they control time-dependent brittle processes and the long-term stability of rocks. In this paper, we present ...
-
(Doctoral thesis / Doktoravhandling, 2019)Silicon purification technologies based on monosilane pyrolysis hold the potential to significantly reduce the energy consumption and cost related to production of solar grade silicon for the photovoltaic industry. These ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Nuclear reactions where an exotic nucleus captures a neutron are critical for a wide variety of applications, from energy production and national security, to astrophysical processes, and nucleosynthesis. Neutron capture ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Reaction-infiltration instability refers to the morphological instability of a reactive fluid front flowing in a soluble porous medium. This process is important for many naturally occurring phenomena, such as the weathering ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We present the first experimental evidence of the scissors mode in the superheavy nucleus 254No produced in the 208Pb(48Ca, 2nγ))254No reaction. The spectrum of γrays emitted by the excited 254No nuclei shows an enhanced ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)As experimental neuroscience is moving toward more integrative approaches, with a variety of acquisition techniques covering multiple spatiotemporal scales, data management is becoming increasingly challenging for neuroscience ...
-
(Doctoral thesis / Doktoravhandling, 2023)Ischemia-reperfusion injury (IRI) has long been a challenge in organ transplantation and general surgery. Disorders characterized by IRI have a high mortality and morbidity rate, where delayed treatment is one of the causes, ...
-
(Doctoral thesis / Doktoravhandling, 2019)Calcium carbonate is one of the most abundant materials found in the Earth’s crust and very often it acts as a natural cement to form several rocks like limestone, chalk and marble. However, despite of its abundance and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Plasma wakefield dynamics over timescales up to 800 ps, approximately 100 plasma periods, are studied experimentally at the Advanced Wakefield Experiment (AWAKE). The development of the longitudinal wakefield amplitude ...
-
(Master thesis / Masteroppgave, 2008)Stylolites are features of localized dissolution in sedimentary rocks. They are planes oriented normal to the compaction direction and have a rough and often teeth-like surface structure. The vertical spacing of individual ...
-
(Master thesis / Masteroppgave, 2020)The present thesis makes a specific focus on the experimental study of the pygmy dipole resonance (PDR) in $^{124}$Sn and its evolution with increasing number of neutrons for the $^{116-119,121,122}$Sn and $^{124}$Sn ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The element distribution that we observe in the Universe today tells a fascinating story of nucleosynthesis events that have taken place throughout the 13.7-billion-years-long history starting with the Big Bang. It has ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)The nuclear level density and the γ -ray strength function have been extracted for 89Y by using the Oslo method on 89Y(p,p γ ) 89Y coincidence data. The γ -ray strength function displays a low-energy enhancement consistent ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The wake behind a spherical microparticle in a magnetized ion flow is studied experimentally by analyzing the arrangement of a pair of particles. It is shown that there are two stable particle arrangements at intermediate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Objective. Gradient-based optimization using algorithmic derivatives can be a useful technique to improve engineering designs with respect to a computer-implemented objective function. Likewise, uncertainty quantification ...
