SAMURAI workshop

SAMURAI analysis update

The nuclear structure in the “island of inversion“ is dominated by pf-intruder configurations. Recent measurements aimed to find out how far these shell-structure changes extend to the lower Z region. We performed the invariant-mass spectroscopy of 30F and the excited states in 29F, first results will be shown. Two-neutron correlations are also studied in the latter case.

Sonja Storck (TU Darmstadt)

03/09/2018, 18:05

SAMURAI workshop

SAMURAI analysis update

A recent experiment suggests that the ground state of the neutron-unbound nucleus ${}^{\text{26}}$O could have a lifetime in the pico-second regime. This would constitute the first case of a radioactive decay via neutron emission, if this value can be confirmed.

In Dezember 2016, an experiment using a new measurement method to determine the decay lifetime of the ${}^{\text{26}}$O ground state with...

Didier Beaumel (IPN Orsay / RIKEN Nishina center)

04/09/2018, 15:10

The Samurai12 experiment has been performed during the last spring campaign. Cluster structure of the ground-state of neutron-rich Beryllium isotopes was investigated using the (p,p alpha) reaction in inverse kinematics. Multineutron spectra should also be accessible from the same data. A brief description of the setup will be given and few preliminary spectra from the (early stage) data...

9. Status report of the analysis of the ${}^6$He($p$,$p^{\prime }\alpha$)${}^{2}n$-channel

SAMURAI analysis update

A status report of the analysis of the ${}^6$He($p$,$p^{\prime }\alpha$)${}^{2}n$-channel from the S19 experiment in 2017 is given. The alpha-knockout reaction channel can be used to investigate the properties of the dineutron system. Besides the current status, upcoming steps of the further analysis are presented which have to be done to calculate the corresponding relative energy spectrum.

SAMURAI workshop

SAMURAI analysis update

The heaviest bound helium isotopes ${}^6$He and ${}^8$He are 2- and 4-neutron halo nuclei with a clear alpha plus 2n and 4n structure. After electromagnetic excitation, they mainly decay via two- and four-neutron emission.
In July 2017, the SAMURAI37 experiment was performed with the purpose of measuring the multi-neutron decay of ${}^6$He and ${}^8$He after heavy-ion-induced electromagnetic...
