First measurement of the antihydrogen production cross section through the charge-exchange reaction of low-energy antiprotons with orthopositronium

GBAR Collaboration, P. Adrich, I. Belosevic +42

The GBAR experiment has measured the formation rate of antihydrogen from antiproton impact on a positronium cloud for antiproton kinetic energies of 4 and 6 keV. This is the first…

Monitoring antiproton numbers with a CMOS detector in a dense-track environment

C. Regenfus, P. Adrich, I. Belosevic +42

The production of antihydrogen by the GBAR experiment at AD/ELENA requires good knowledge of the number of incident keV antiprotons, which can be problematic. We have used a commer…

A determination of the backscattering probability of low-energy antiprotons

GBAR Collaboration, K. Park, E. Perez +42

It is commonly assumed that antiprotons impinging on a material surface annihilate promptly with the nuclei of the material. However, at kinetic energies of a few keV, this assumpt…

Record accumulation of antiprotons in a Penning-Malmberg Trap and their preparation for improved production of antihydrogen beams

B. Lee, B. Kim, P. Adrich +35

CERN's AD/ELENA ``antimatter factory'' - unique worldwide - serves several experiments, all of which use electromagnetic traps to accumulate antiprotons for fundamental science. Th…

Observation of a broad -wave resonant state in He

Y. L. Sun, A. Corsi, Y. Kubota +63

We report on the two-body invariant-mass spectroscopy of He, populated via the 11 knockout reaction from the two-neutron halo nucleus Li at 250 MeV/nucleon…

Evolution of two-neutrons configuration from 11Li to 13Li

P. Andrè, A. Corsi, A. Revel +69

In this work we investigate the two-neutron decay of 13Li and of the excited states of 11Li populated via one-proton removal from 14Be and 12Be, respectively. A phenomenological mo…

Mass, spectroscopy and two-neutron decay of Be

B. Monteagudo, F. M. Marqués, J. Gibelin +65

The structure and decay of the most neutron-rich beryllium isotope, Be, has been investigated following proton knockout from a high-energy B beam. Two relatively narr…

Searching for universality of dineutron correlation at the surface of Borromean nuclei

A. Corsi, Y. Kubota, J. Casal +65

The dineutron correlation is systematically studied in three different Borromean nuclei near the neutron dripline, 11Li, 14Be and 17B, via the (p, pn) knockout reaction measured at…

Positron accumulation in the GBAR experiment

P. Blumer, M. Charlton, M. Chung +67

We present a description of the GBAR positron (e+) trapping apparatus, which consists of a three stage Buffer Gas Trap (BGT) followed by a High Field Penning Trap (HFT), and discus…

Quasi-free Neutron Knockout Reaction Reveals a Small -orbital Component in the Borromean Nucleus B

Z. H. Yang, Y. Kubota, A. Corsi +73

A kinematically complete quasi-free experiment in inverse kinematics was performed to study the structure of the Borromean nucleus B, which had long been considered…

Surface localization of the dineutron in Li

Y. Kubota, A. Corsi, G. Authelet +64

The formation of a dineutron in the nucleus Li is found to be localized to the surface region. The experiment measured the intrinsic momentum of the struck neutron in $^{11}…

Positron production using a 9 MeV electron linac for the GBAR experiment

M. Charlton, J. J. Choi, M. Chung +67

For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses…

Ni revealed as a doubly magic stronghold against nuclear deformation

R. Taniuchi, C. Santamaria, P. Doornenbal +68

Nuclear magic numbers, which emerge from the strong nuclear force based on quantum chromodynamics, correspond to fully occupied energy shells of protons, or neutrons inside atomic…

Structure of 13Be probed via quasi-free scattering

A. Corsi, Y. Kubota, J. Casal +65

We present an investigation of the structure of 13Be obtained via a kinematically complete measurement of the (p; pn) reaction in inverse kinematics at 265 MeV/nucleon. The relativ…

The COMPASS Setup for Physics with Hadron Beams

Ph. Abbon, C. Adolph, R. Akhunzyanov +228

The main characteristics of the COMPASS experimental setup for physics with hadron beams are described. This setup was designed to perform exclusive measurements of processes with…
