Abstract

A new double-sided silicon strip detector has been developed to study the phenomenon of ground-state proton radioactivity. Highly proton-rich fusion-evaporation reaction products are velocity and mass separated using the Daresbury recoil separator before being implanted into the strip detector located at the separator focal plane. The double-sided strip detector has 48 strips per face with a pitch of 335 μm. Front and back strips are orthogonal providing an effective pixel area of 0.09 mm², enabling correlations between implanted ions and subsequent decays to be clearly established. Test results obtained using the reactions $^{58} Ni +^{92} Mo →^{150} Yb^{∗} and^{58} Ni +^{54} Fe →^{112} Xe^{∗}$ are reported. In the latter commisioning experiment the proton decay of ¹⁰⁹I was unambiguously established using the correlated decay sequence ¹⁰⁹I→^p¹⁰⁸Te→^α¹⁰⁴Sn.

Novel device to study double-alpha decay at the FRS Ion Catcher
2024, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
A novel system has been developed to detect simultaneous double-alpha emission from purified and weightless sources. The system includes the collection of ²²⁴Ra low-energy recoils in purified helium buffer gas from the decay of ²²⁸Th. The recoil products are thermalized and collected in a cryogenic buffer gas cell and extracted into an RF-ion guide for mass selection. The mass-separated ions are implanted at low kinetic energy into a thin carbon foil placed between two large-area double-sided silicon strip detectors to observe correlated alpha-particle emission. The apparatus is described in detail, including insights into its experimental performance.
Two-proton emission and related phenomena
2023, Progress in Particle and Nuclear Physics
One of characteristic phenomena for nuclei beyond the proton dripline is the simultaneous emission of two protons (2p). The current status of our knowledge of this most recently observed and the least known decay mode is presented. First, different approaches to theoretical description of this process, ranging from effective approximations to advanced three-body models are overviewed. Then, after a brief survey of main experimental methods to produce 2p-emitting nuclei and techniques to study their decays, experimental findings in this research field are presented and discussed. This review covers decays of short-lived resonances and excited states of unbound nuclei as well as longer-lived, ground-state radioactive decays. In addition, more exotic decays like three- and four-proton emission are addressed. Finally, related few-body topics, like two-neutron and four-neutron radioactivity, and the problem of the tetraneutron are shortly discussed.
The Advanced Implantation Detector Array (AIDA)
2023, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
The Advanced Implantation Detector Array (AIDA) is a state-of-the-art detector system for the measurement of the decay properties of exotic nuclei at fragmentation/fission facilities. Built around stacks of up to eight $8 cm \times 8 cm$ , 128 × 128 strip (16384 pixels) or up to four $24 cm \times 8 cm$ , 384 × 128 strip (49152 pixels) double sided silicon strip detectors, the positions of both implanted ions and their subsequent decay products can be measured to sub-mm precision. The large number of pixels per detector provide implant-decay correlations at implantation rates $\sim$ kHz. To process signals from the large number of strips application specific integrated circuits provide low and high gain signal processing per strip (20 GeV and 20 MeV full scale range) with a dynamic range of 1000:1, or better. A summary of the system and the analysis methodologies used are presented.
Nuclear structure studies with re-accelerated beams at REX-and HIE-ISOLDE
2020, Progress in Particle and Nuclear Physics
Nuclear-structure studies with reaccelerated radioactive ion beams at the ISOLDE facility, CERN commenced with the REX-ISOLDE facility and continued after a major upgrade of the facility with the HIE-ISOLDE post-accelerator. The experiments are based on in-beam high-resolution $γ$ -ray spectroscopy with Miniball, a spectrometer which comprises 24 six-fold segmented, encapsulated high-purity germanium crystals. The Miniball array has been used in Coulomb excitation and transfer-reaction experiments with exotic ion beams of energies up to 10 MeV/u. The investigations cover a wide range of nuclear structure topics which are addressed with beams ranging from beryllium up to heavy radium isotopes. Experimental conditions improved substantially after commissioning of the HIE-ISOLDE project at CERN with higher secondary-beam intensity, higher beam energy and better beam quality. We review the spectroscopy achievements obtained at REX-ISOLDE and first published results from HIE-ISOLDE.
Measurement of the branching ratio for β-delayed α decay of <sup>16</sup>N
2016, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
While the ${}^{12}C {(α, γ)}^{16} O$ reaction plays a central role in nuclear astrophysics, the cross section at energies relevant to hydrostatic helium burning is too small to be directly measured in the laboratory. The β-delayed α spectrum of ¹⁶N can be used to constrain the extrapolation of the E1 component of the S-factor; however, with this approach the resulting S-factor becomes strongly correlated with the assumed βα branching ratio. We have remeasured the βα branching ratio by implanting ¹⁶N ions in a segmented Si detector and counting the number of βα decays relative to the number of implantations. Our result, $1.49 (5) \times 10^{- 5}$ , represents a $24 %$ increase compared to the accepted value and implies an increase of $\approx 10 %$ in the extrapolated S-factor.
Implantation-decay station for low-energy β-delayed proton measurements
2013, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
We have built an implantation-decay station for $β - delayed$ proton and $α$ decay studies at the focal plane of the Momentum Achromat Recoil Spectrometer (MARS) at the Cyclotron Institute of Texas A&M University. Energetic secondary beams with a small momentum spread are stopped in a controlled manner into a very thin silicon strip detector. In addition, high-purity germanium detectors are installed for $γ$ ray detection. Here we give a description of the setup and the observed performance down to $E_{p} \approx 200 keV$ using implanted ²³Al and ³¹Cl sources.
