Transfer reactions are pivotal in nuclear structure and reaction studies. In heavy-ion transfer reactions, multiple nucleons can be transferred in a single collision along with significant energy and angular momenta from the relative motion to the intrinsic degrees of freedom [1,2]. This establishes multinucleon transfer reactions as an essential tool for probing a wide array of topics, from...
The COLLAPS experiment stands at the forefront of collinear laser spectroscopy, a field dedicated to the precise measurement of unique nuclear characteristics in short-lived and exotic radioactive nuclei. By analyzing hyperfine structures and isotope shifts, it determines nuclear spins, electromagnetic moments, and charge radii.
At its core, COLLAPS seeks to unravel the mysteries surrounding...
Nuclei in the vicinity of doubly-magic nuclei, such as $^{78}$Ni, are of considerable interest for studying the evolution of shell structure within the nuclear shell model. Understanding this evolution is essential for accurately describing exotic nuclear phenomena. In particular, the shape coexistence in $^{79}$Zn makes this region especially intriguing, given that such a phenomenon is...
We study the shape coexistence in the nucleus $^{28}$Si with the nuclear shell model using numerical diagonalizations complemented with variational calculations based on the projected generator-coordinate method. Although the ground-state oblate rotational band is well described in the $sd$ shell by the USDB interaction, the second excited $0^+_3$ state and higher-energy levels lack the...
Neutron-rich nuclei in the A=100 mass region display a large variety of shape coexistence phenomena dominating their structure and dynamics. Multifaceted impact of shape coexistence is revealed in the structural evolution with spin, excitation energy, and neutron number, the appearance of the isomeric states, their exotic decay including allowed and first-forbidden β decay. We studied the...
