α particles in stable nuclei Decay is a common mode of radioactivity heavy elements such as uranium that entails the loss comprising two protons and neutrons. Despite more than century study, when where these form unstable alike remains an open question. Tanaka et al. bombarded series tin isotopes with high-energy detected ejected at abundance inversely correlated mass number (see Perspective by Hen). This observation, relating particle accumulation to neutron skin thickness nuclear surface,...
Abstract The shape and internal structure of an atomic nucleus can change significantly with increasing excitation energy, angular momentum, or isospin asymmetry. As example this structural evolution, linear-chain configurations in carbon heavier isotopes have been predicted for decades. Recent studies found non-stability 12 C while evidenced its appearance 16 C. It is then necessary to investigate the molecular structures 14 clarify exact location on nuclear chart where begins emerge, thus...
An experiment for p(14C,14C* → 10Be+ α)p inelastic excitation and decay was performed in inverse kinematics at a beam energy of 25.3 MeV/u. A series 14C excited states, including new one 18.3(1) MeV, were observed which to various states the final nucleus 10Be. specially designed telescope system, installed around zero degrees, played an essential role detecting resonant near α-separation threshold. state 14.1(1) MeV is clearly identified, being consistent with predicted band-head molecular...
In a reaction to excite the resonant state followed by sequential cluster-decay, in-plane angular correlation method is usually applied determine spin of mother nucleus. However, pattern exhibited in two-dimensional angular-correlation spectrum depends on selected coordinate system. Particularly parity-symmetric and axial-symmetric processes should be presented way enhance whereas non-symmetric process plotted elsewhere order reduce background. this article, three possible systems, which...
