All even-even nuclei possess excited 0+ states. Often, they are poorly characterized because they can be difficult to populate. However, the identification of 0+ states and the characterization of their properties is critical to the elucidation of the structure of all even-even nuclei. Examples at both closed and open shells will be selected to illustrate this aspect of nuclear structure explorati ... More

The discovery of nuclear molecules [1], double nuclear system and deep inelastic transfer reactions [2, 3] allow a new interpretation to be proposed for the cluster formation mechanism. It is assumed that nuclei of elements heavier than lead are capable of spontaneously condensing valence nucleons (nucleons above 208Pb) to nuclei of lights elements – clusters. This process results in formation ... More

The shell structure at N = 82 plays a crucial role for the rapid neutron capture (r-) process. For example, it determines the shape of the large A∼130 peak in the solar system abundance pattern and affects the timescale of the r-process as well as the amount of neutrons later available for induced fission. However, below Z = 50 the evolution of the N = 82 gap is still unknown and, therefore, the ... More

Cluster decay is a kind of radioactivity in which the emitted nuclei are heavier than alpha particle but lighter than the binary fission fragments. This is one of the famous phenomena which have been predicted theoretically before to be confirmed experimentally. This is because this type of decay occurs in nuclei that decay primarily by alpha emission. The branching ratios relative to alpha decay ... More

The effect of the electron screening on the alpha decay rate of typical nuclei is considered. To this end, the adiabatical approach is exploited, which consecutively takes into account the adiabaticity of the motion of the alpha particle through the shells [1]. The effect is found to be of the order of one tenth to one hundredth of a percent for the considered representative nuclei. The method can ... More

It is well known that simple monopole pairing is a pretty crude approximation. It can account for the observations that the ground states of all even-even nuclei have spin-parity 01+ and that there is a pairing gap above the ground state in deformed nuclei before particle-hole (p-h) configurations can be excited. As an approximation it is best for proton and neutron mid-shell nuclei where the avai ... More

The DIAMANT light-charged-particle detector from ATOMKI has been coupled with the AFRODITE gamma-ray spectrometer at iThemba LABS in a collaboration enabled by a bilateral agreement between the governments of South Africa and Hungary. This has facilitated the study of incomplete fusion reactions in the bombardment of a Ytterbium-176 target with a beam of 50 MeV Lithium-7 ions. The beam was generat ... More

Two-nucleon transfer, such as (p,t) and (p,3He) reactions on stable nuclei, was studied extensively in the past, thereby successfully revealing crucial properties of stable nuclei. For unstable target systems this type of reaction also promises to be especially useful. However, a theoretical description of the reaction in terms of the distorted-wave Born approximation suffers from several problems ... More

Precision measurements of electromagnetic transition rates provide accurate inputs into nuclear data evaluations and are also used to test and validate predictions of state of the art nuclear structure models. Measurements of transition rates can be used to ascertain or rule out multipolarity assignments for the measured EM decay, thereby providing spins and parity (difference) information for st ... More
