<p>Nuclear structure can be uniquely probed by beta-decay experiments, being highly selective, and capable of providing information for nuclei far away from stability. One open question in nuclear-astrophysics which may be addressed by $\beta$-decay measurements is the rapid neutron capture nucleosynthesis process.</p>
<p>For this thesis, a novel $\beta$ detector was specially designed and fabricated for $\beta$-decay spectroscopy at the IGISOL-4 facility, University of Jyväskylä, Finland. In experiments, a purified isotope beam will be implanted on a tape and $\beta$-decays will be detected by this detector. In addition, low energy HPGe detectors will be placed surrounding the $\beta$ detector to enable simultaneous $\gamma$-ray spectroscopy.</p>
<p>The developed $\beta$ detector incorporates a thin plastic scintillator with a spherical shell geometry to maximize solid angle coverage (3.7$\pi$). Photodetectors of silicon photomultipliers (SiPM) are integrated along the edges and are supported by self-made PCBs. Low x-ray attenuation is achieved with the scintillator having a thickness of only 1.0 mm and permits the detection of x-rays generated in $\beta$-decay by surrounding HPGe gamma detectors with low transmission loss. To match the dynamic range of digitizers and standard NIM electronics it is necessary for pulses from the SiPMs to be amplified. For this reason, an 8 channel ultra-fast preamplifier was custom built utilizing MMICs (Monolithic microwave integrated circuits). The preamplifier incorporated bias regulation and noise filtering. All $\beta$-detector parts were self-fabricated at the University of Jyväskylä. In addition, a procedure to recover position information with post-processing of the SiPM signals from different amplitudes of the quadrants was demonstrated.</p>

<p>The nature of the atomic nucleus as a quantum many-body system leads to the emergence of microscopic properties. One such property, the observation of magic numbers of nucleons has permitted the development of the independent-particle shell model of the nucleus. These magic numbers of nucleons, which appear as large energy gaps in the spherical nuclear shell model, is known to erode in asymmetric nuclear systems far from nuclear stability.</p>
<p>The evolution of this behavior was studied in at, and near, magic neutron numbers $\textrm{N}=20$ and $\textrm{N}=28$ in neutron-rich neon (\(\ce{^{32}Ne}\)) and aluminum (\(\ce{^{39,-41}Al}\)). Nuclear collectivity and excited state structure was deduced by in-beam gamma-ray spectroscopy of knockout reactions and inelastic scattering.</p>
<p>The experiments were carried out at the RIKEN Nishina Center, RIBF. A coupled set of linear and cyclotron accelerators were used to generate a high energy beam of \(\ce{ ^{48}Ca+}\) at $345\; \textrm{MeV}\textrm{u}^{-1}$. This beam impinged on a target, producing a radioactive ion beam, of many species, via projectile fragmentation. The magnetic separator BigRIPS was used to both filter these isotopes and provide event-by-event isotope identification by in-beam time-of-flight and energy loss detectors. At the end of BigRIPS, an additional target was placed to induce secondary nuclear reactions producing \(\ce{^{32}Ne}\) and \(\ce{^{39,40,41}Al}\) nuclei in excited states. These states decay promptly by $\gamma$ emission and the DALI2 detector array, surrounding the secondary target, detected these $\gamma$-rays.</p>
<p>The reconstructed $\gamma$-ray spectra, corrected for relativistic effects, revealed new nuclear structure of \(\ce{^{32}Ne}\) and \(\ce{^{39,40,41}Al}\). For \(\ce{^{32}Ne}\), a new transition was assigned to a $4^+\rightarrow2^+$ transition. Shell-model calculations with large valence spaces were performed and the predicted states are in agreement with the experimentally assigned $2^+$ and $4^+$ levels. The observed states and ground state are predicted to be almost pure intruder configurations and composed mainly of 2p-2h and 4p-4h components. Furthermore, the deduced large $R_{4/2}$ ratio of 2.99(6) indicates a continuing trend of increasing collectivity for $N>20$ in neon and additional evidence of this nuclide in the so-called island of inversion. Lastly, inclusive and exclusive cross sections of one- and two-proton knockout reaction cross sections to \(\ce{^{32}Ne}\) revealed a significant suppression factor and extend systematics for neon isotopes and more generally as a function of nuclear asymmetry. For \(\ce{^{39,40,41}Al}\) isotopes, new energy levels were tentatively proposed and suggest a high degree of deformation near magic $N=28$.</p>
