في تجربة أجريت في مرفق SPIRAL1 من GANIL، تم دراسة فكرة التحلل البيتا ل 32Ar باستخدام جهاز Silicon Cube المرتبط بمستشعرات germanium clover من مجموعة EXOGAM. تم الكشف عن الذرات البيتا المتأخرة البروتونية والجاما، والتي أثبتت تحديد كافة الشوائب المتحللة المتعلقة. تم مقارنة توزيع قوة Gamow-Teller بحسابات النموذج القطعي وتم العثور على توافق ممتاز. كما أن قوة Fermi كانت تتوافق مع التوقعات. وتم إنشاء برنامج تحلل كامل تقريبا ل 32Ar.
In an experiment performed at the SPIRAL1 facility of GANIL, the beta decay of 32Ar has been studied by means of the Silicon Cube device associated with germanium clover detectors from the EXOGAM array. Beta-delayed protons and gamma rays have been observed and allowed the determination of all relevant decay branches. The Gamow-Teller strength distribution is compared to shell-model calculations and excellent agreement is found. The Fermi strength is inline with expectations. A quasi-complete decay scheme of 32Ar is established.
We report on high-statistics data from the $beta^-$ decay of the $^{46}$K $J^{pi}$ = 2$^-$ ground state taken with the GRIFFIN spectrometer located at the TRIUMF-ISAC facility. In total, 199 $gamma$ rays and 42 excited states were placed in the level
A beta-decay study of Cu-77 has been performed at the ISOLDE mass separator with the aim to deduce its beta-decay properties and to obtain spectroscopic information on Zn-77. Neutron-rich copper isotopes were produced by means of proton- or neutron-i
A new technique was developed to measure the lifetimes of neutron unbound nuclei in the picosecond range. The decay of 26O -> 24O+n+n was examined as it had been predicted to have an appreciable lifetime due to the unique structure of the neutron-ric
The full data set of the NEMO-3 experiment has been used to measure the half-life of the two-neutrino double beta decay of $^{100}$Mo to the ground state of $^{100}$Ru, $T_{1/2} = left[ 6.81 pm 0.01,left(mbox{stat}right) ^{+0.38}_{-0.40},left(mbox{sy
The kinematics of two-neutron emission following the $beta$-decay of $^{11}$Li was investigated for the first time by detecting the two neutrons in coincidence and by measuring their angle and energy. An array of liquid-scintillator neutron detectors
