(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Nuclear level densities (NLDs) and γ -ray strength functions (GSFs)of 120;124 Sn have been extracted with the Oslo method and additionally constrained with the novel Shape method. The GSFs were found to be in excellent ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The nuclear level densities (NLDs) and γ-ray strength functions (GSFs) of 120,124Sn were extracted with the Oslo method, compared and combined with other experimental data to be used as inputs in the TALYS reaction code ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Particle- γ coincidence experiments were performed at the Oslo Cyclotron Laboratory with the 181 Ta ( d , X ) and 181 Ta ( 3 He , X ) reactions to measure the nuclear level densities (NLDs) and γ -ray strength functions ...

Nuclear level densities and γ-ray strength functions of 180,181Ta and neutron capture cross sections (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The γ -ray strength functions and nuclear level densities in the quasi-continuum of 180,181Ta are extracted from particle-γ coincidence events with the Oslo Method, below the Sn . The data were used as input in the TALYS ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The nuclear level density (NLD) and γ-ray strength function (γSF) of 63Ni have been investigated using the Oslo method. The extracted NLD is compared with previous measurements using particle evaporation and those found ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Neutral pion(π0) and ηmeson production cross sections were measured up to unprecedentedly high transverse momenta(pT) in p–Pbcollisions at √sNN=8.16 TeV. The mesons were reconstructed via their two-photon decay channel in ...
-
(Doctoral thesis / Doktoravhandling, 2024)How does the structure of neutron-rich atomic nuclei change when moving away from stability? Here, both single-particle and collective effects are studied by using two case studies: the chain of neutron-rich copper isotopes ...
-
(Master thesis / Masteroppgave, 2016)Nuclear level densities and γ-ray strength functions are essential quantities in various fields of basic and applied research involving nuclear matter. From microscopic calculations and structure research to nuclear reactor ...
-
(Doctoral thesis / Doktoravhandling, 2009)This dissertation presents the measurement of level densities and y-ray strength functions of selected warm nuclei in the vicinity of closed and near closed shells. These quantities are important for their application ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The nuclear structure of the 76 Ni nucleus was investigated by ( p , 2 p ) reaction using a NaI(Tl) array to detect the deexciting prompt γ rays. A new transition with an energy of 2227 keV was identified by γ γ and γ ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Newly observed decay schemes of the nuclei 137Sb and 138Sb are reported. The neutron-rich Sb isotopes were produced by the in-flight fragmentation of a 238U primary beam with an energy of 345 MeV/nucleon. Several new excited ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Stability of the vortex matter—magnetic flux lines penetrating into the material—in type-II superconductor films is crucially important for their application. If some vortices get detached from pinning centres, the energy ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Fluid-induced alteration of rocks and mineral-based materials often starts at confined mineral interfaces where nm-thick water films can persist even at high overburden pressures and at low vapor pressures. These films ...
-
(Master thesis / Masteroppgave, 2012)Frost damage in trees is caused when bubbles released from thawing ice cavitate due to the low, and often negative, pressure in trees. This thesis presents the development of a method for in situ observations of such ...
-
(Master thesis / Masteroppgave, 2022)I søket etter ny fysikk videre etter standard modellen brukes det mye tid på å regne ut det samme tverrsnittet flere ganger. Spesielt for kollisjoner som involverer protoner så er parton distribusjon funksjonene veldig ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The role of spatial resolution of the electron gyroradius in electrostatic particle-in-cell (PIC) simulations is studied. It is demonstrated that resolving the gyroradius is crucial for simulations of strongly magnetized ...
