| Summary: | My Master Thesis is titled “Determination of the fission half-life for the
isotope 250No”. The data I analyse in this work were collected in an experiment
run in April, 2015, at the accelerator laboratory of the University of Jyväskylä.
The Physics motivation for the experiment is explained in my thesis, as well as
the involved theoretical background.
This isotope was previously proven to decay via spontaneous fission. Also an
isomeric state was found. The question I give an answer to in my work is
whether the isomeric state fissions directly or it gamma-decays to the ground
state, which then fissions itself. Besides both half-lives (for the ground state and
the isomeric state) were calculated.
The data acquisition was performed both with analogic and digital channels,
allowing to extrapolate decay digital traces. Given that two different half-life
components are present, a shorter one for the ground state and a longer one for
the isomeric state, I utilized a K.H.Schmidt analysis to separate the two
components. The traces for the short component were instead analysed with a
moving window deconvolution method.
I found new and very interesting results, with great satisfaction of myself and my
supervisor, who would like to publish them afterwards.
