The decays of the $\beta$-delayed neutron emitters $^{137}$I and $^{95}$Rb have been studied with the total absorption $\gamma$-ray spectroscopy technique. The purity of the beams provided by the JYFLTRAP Penning trap at the ion guide isotope separator on-line facility in Jyv\"askyl\"a allowed us to carry out a campaign of isotopically pure measurements with the decay total absorption $\gamma$-ray spectrometer, a segmented detector composed of eighteen NaI(Tl) modules. The contamination coming…

Enhanced γ-Ray Emission from Neutron Unbound States Populated in β Decay.

TLDR
Total absorption spectroscopy is used to investigate the β-decay intensity to states above the neutron separation energy followed by γ-ray emission in (87,88)Br and (94)Rb, and an unexpectedly large γ intensity is observed in all three cases extending well beyond the excitation energy region where neutron penetration is hindered by low neutron energy.

Strong Neutron-γ Competition above the Neutron Threshold in the Decay of ^{70}Co.

TLDR
The β-decay intensity of ^{70}Co was measured for the first time using the technique of total absorption spectroscopy and the data are compared to two theoretical calculations: the shell model and the quasiparticle random phase approximation (QRPA).
