Recently, the LIGO Virgo Collaboration achieved the first detections of a gravitational waves. A century after the fundamental predictions of Einstein, we report the first direct observations of binary black hole systems merging to form single black holes. The detected waveforms match the predictions of general relativity for the inspiral and merger of a pair of black holes and the ringdown of...
The level scheme of 213Fr was investigated for the first time through γ-ray spectroscopy at ISOLDE, CERN. An A=232 molecular beam of 213Ra+19F was sent to the ISOLDE Decay Station setup, where γ-rays and charged particles were detected using HPGe clover detectors and DSSSDs, respectively. Low-spin excited states in the semi-magic 213Fr (N=126) were populated in the EC/β+ decay of the 1/2-...
Study the east region around the doubly magic $^{208}$Pb, represents an ideal testing ground to understand the effects related to the effective three-body forces, i.e., if the large calculations are feasible and the seniority scheme provides useful guidance. However, this region of the Segrè chart has been traditionally difficult to access experimentally due to its neutron richness and low...
$^{208}$Pb is the heaviest stable doubly-magic nucleus and has been studied in great detail. Its first excited state occurs at 2.6 MeV and corresponds to an octupole vibration, resulting from the collective behaviour of a number of E3 ($\Delta l = \Delta j = 3$) particle excitations across the closed shell. This octupole transition has been observed in several other nuclei around $^{208}$Pb,...
