Abstract

An experiment to the search for very neutron-rich nuclei has been performed at RIKEN, using projectile fragmentation of an intense 64 A MeV ⁴⁸Ca beam and the fragment separator RIPS. Three new neutron-rich isotopes, ³⁴Ne, ³⁷Na and ⁴³Si were observed unambiguously for the first time, and convincing evidence for the particle instability of three others, ³³Ne, ³⁶Na and ³⁹Mg was obtained. The experimental findings are discussed in comparison with recent theoretical predictions.

Nuclear Structure and Decay Data for A=31 Isobars
2022, Nuclear Data Sheets
Experimental nuclear spectroscopic data are evaluated for 11 known nuclides of mass 31 (F, Ne, Na, Mg, Al, Si, P, S, Cl, Ar, K). Detailed evaluated information is presented for each reaction and decay experiment. Combining all the available data, recommended values are provided for energies, spins and parities, and half-lives of levels, with energies, branching ratios and multipolarities of γ radiations, and characteristics of β and α radiations in radioactive decays. ³¹P is the most extensively studied one among all nuclides via various reactions and decays, followed by ³¹S, ³¹Si, ³¹Mg and ³¹Al. Information for excited states in ³¹Ne, ³¹Na, ³¹Cl, ³¹Ar and ³¹K are limited; no excited states have yet been identified in ³¹F, even its ground-state half-life is unknown. Significant new data have become available for the structure of ³¹S, with its relevance to astrophysical applications. This work supersedes the earlier evaluation of A=31 by 2013Ou01, with literature cutoff date of Feb 15, 2013.
Exotic nuclei explored at in-flight separators
2017, Progress in Particle and Nuclear Physics
In-flight separators have played a significant role in the physics of exotic nuclei. In the last decade, in particular, this field has expanded rapidly with the advent of the new-generation (3rd-generation) in-flight-separator facility, the RI-beam Factory (RIBF) at RIKEN that was commissioned in 2007. In addition, new experimental methods, techniques and state-of-the-art detectors at in-flight separators have developed rapidly, which has contributed considerably to this progress. One can now reach very far from the stable nuclei towards the drip lines, and even beyond in some cases. Hundreds of new isotopes have been identified, and new exotic isomers have been observed. $β$ decays and relevant $γ$ decays, including isomeric states, have clarified many new aspects of nuclear structures. A variety of direct reactions, making the best use of in-flight rare isotope (RI) beams at intermediate/high energies, have been applied for a wide range of rare isotopes. New experimental results using these methods have shown that one needs a new framework to understand structures and dynamics of exotic nuclei, such as new or lost magic numbers, novel neutron halo/skin structures and relevant reactions/excitations. A wide range of reactions associated with nucleo-synthesis in the Universe and the equation of state (EoS) of neutron-rich nuclear matter have also been studied through experiments using rare isotopes available at in-flight separators. This review article focuses its attention on how recent experimental techniques have been developed and applied to exotic nuclei at in-flight separators. We also make remarks on prospects for the near future: in the era when the 3rd-generation RI-beam facilities based on in-flight separators are being completed world-wide.
Nuclear Data Sheets for A=40
2017, Nuclear Data Sheets
The experimental nuclear structure data and decay data are evaluated for the known nuclides of mass 40 (Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti). Detailed evaluated nuclear structure information is presented with the best values recommended for level energies, half-lives, γ-ray energies and intensities, decay properties (energies, intensities and placement of radiations), and other spectroscopic data. The ⁴⁰Ca and ⁴⁰K nuclides remain as the most extensively studied from many different reactions and decays; no excited states are known in ⁴⁰Mg, ⁴⁰Al, ⁴⁰P and ⁴⁰Ti. This work supersedes the earlier full evaluation of A=40 by J. Cameron and B. Singh (2004Ca38).
Evaluation of Beta-Delayed Neutron Emission Probabilities and Half-Lives for Z = 2-28
2015, Nuclear Data Sheets
We present an evaluation and compilation of β-delayed neutron probabilities and half-lives for nuclei in the region Z = 2–28 (⁸He–⁸⁰Ni). This article includes the recommended values of these quantities as well as a compiled list of experimental measurements for each nucleus in the region for which β-delayed neutron emission is possible. The literature cut-off for this work is August 15^th, 2015. Some notable cases as well as new standards for β-delayed neutron measurements in this mass region are also discussed.
Nuclear Data Sheets for A = 43
2015, Nuclear Data Sheets
The experimental data are evaluated for known nuclides of mass number A = 43 (Al,Si,P,S,Cl,Ar,K,Ca,Sc,Ti,V,Cr). Detailed evaluated level properties and related information are presented, including adopted values of level and γ–ray energies, decay data (energies, intensities and placement of radiations), and other spectroscopic data. This work supersedes earlier full evaluations of A = 43 published by 2001Ca24 and 1990En08 (also 1978En04, and 1998En04 update).
No excited states are known in ⁴³Al, ⁴³Si and ⁴³Cr. Only one excited state is known in ⁴³V which is the probable the Isobaric Analog State (IAS) of ⁴³Cr ground state. Information for ⁴³P, ⁴³S, ⁴³Cl, ⁴³Ar and ⁴³Ti is limited; there is either no decay data available or the decay schemes are incomplete in view of large Q values and known excitations much lower than allowed by Q values. The ⁴³K, ⁴³Ca and ⁴³Sc nuclides remain the most extensively studied from many different reactions and decays.
IsoTagger: Identification of isomeric nuclear states produced in fragmentation reactions with radioactive beams
2015, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
Citation Excerpt :
Projectile fragmentation is a very powerful method to produce nuclei far from stability. In particular very exotic nuclei on the neutron-rich side of the valley of stability have been first produced and identified at radioactive beam facilities employing the projectile fragmentation reactions (see for example [3,4]). Due to the high beam velocity thick targets (on the order of mm or more) can be used to maximize the luminosity.
A new method has been developed to detect and identify isomeric states produced in intermediate beam-energy reactions with secondary radioactive beams. Event-by-event identification of the reaction products allows for an unambiguous assignment of isomeric states to certain nuclei produced in fragmentation reactions. This versatile device allows for the identification of isomeric states with lifetimes between 100 ns and several ms. Combined prompt and delayed γ-ray spectroscopy give detailed information on the level schemes of exotic nuclei. This is particularly important in measurements of exclusive reaction cross-sections to several final states in the residue nucleus.
