Studies of ion transport in gases : applications in nuclear physics
This thesis is centred around the principle of the Ion Guide Isotope Separator On-Line (IGISOL). First, ion transportation in the IGISOL gas cell is studied. As the main result, a method is developed to simulate the evacuation of ions from the gas cell. Secondly, decay properties of neutron-deficient 23Al and 58Cu nuclei are examined using the IGISOL facility. The decay properties of 23Al are of astrophysical interest, while 58Cu decay is important for studies of Garnow-Teller strength.

Applications of light-matter interaction in nanosciences
Hakala, Tommi (University of Jyväskylä, 2009)In this thesis, light matter interaction in nanoscale has been studied from various aspects. The interaction between surface plasmon polaritons (SPPs) and optically active organic molecules (Rhodamine 6G, Sulforhodamine ... -
Precision mass measurements beyond ^{132}Sn: Anomalous behaviour of odd-even staggering of binding energies
Hakala, Jani; Dobaczewski, Jacek; Gorelov, Dmitry; Eronen, Tommi; Jokinen, Ari; Kankainen, Anu; Kolhinen, Veli; Kortelainen, Markus; Moore, Iain; Penttilä, Heikki; Rinta-Antila, Sami; Rissanen, Juho; Saastamoinen, Antti; Sonnenschein, Volker; Äystö, Juha (American Physical Society, 2012)Atomic masses of the neutron-rich isotopes 121–128Cd, 129;131In, 130–135Sn, 131–136Sb, and 132–140Te have been measured with high precision (10 ppb) using the Penning-trap mass spectrometer JYFLTRAP. Among these, the ... -
Mass Measurements of Proton-rich Nuclei with JYFLTRAP
Eronen, Tommi (Jagiellonian University, 2011)The Penning trap setup JYFLTRAP, connected to the IGISOL facility, has been extensively used for atomic mass measurements of exotic nuclei. On the proton rich side of the chart of nuclei mass measurements have mostly ... -
Muon-electron lepton-flavor-violating transitions : Shell-model calculations of transitions in 27Al
Kostensalo, Joel; Suhonen, Jouni; Civitarese, O. (American Physical Society, 2018)In this paper we present the results of large-scale shell-model calculations of muon-to-electron lepton-flavorviolating transitions for the case of the target nucleus 27Al. We extend the previous shell-model calculations, done ... -
A study of the helium-jet recoil-transport method and its application to on-line isotope separation
Äystö, Juha (1977)The helium-jet recoil-transport method and its coupling to the isotope separator on-line have been investigated. The dependence of the transport efficiency on several equipment parameters was studied both experimentally ...
