Unexpected increase of 7Be decay rate under compression

RADIOACTIVITY 7Be(EC)[from 7Li(p, n), E=7 MeV at VECC, Kolkata]; measured Eγ, Iγ, half-life using off-line decay of 7Be ions implanted in Pd and Pb foils; deduced unexpected large increase of 7Be decay rate under compression compared to the state-of-the-art density functional calculations. Comparison with previous experimental values. Implications on the calculated 7Be decay rate at the solar core.

Timescale of non-exponential decay for the nuclear β-decay process in a decoherence model

RADIOACTIVITY 60Co(β-); calculated quantum decoherence time and non-exponential decay time scales of nuclear β-decay processes; not feasible to observe non-exponential decay of 60Co on the time scale of 10-22 s, consistent with the experimental results. Proposed that non-exponential decays could be observed from α-particle emitting states from compound nuclei produced in fusion reactions such as 164,167,170Er(28Si, X)192Pb*/194Pb*/196Pb*.

Examination of the fission time of the Z=120 nucleus

NUCLEAR REACTIONS 64Ni(238U, F)120302*, E=6.6 MeV/nucleon; analyzed percentage of long-lived fission component versus the fission time, fission lifetime versus prefission neutron multiplicity using statistical code JOANNE2. Analyzed large difference in the measured lifetime for asymmetric fission of the highly excited Z=120 super-heavy nucleus measured by the atomic and nuclear techniques; deduced that the difference cannot be explained by sensitivity argument of the techniques in different time domains; questioned formation of excited Z=120 nucleus.

Nuclear temperatures from evaporation fragment spectra and observed anomalies

NUCLEAR REACTIONS 89Y(16O, X), E=96 MeV; 93Nb(12C, X), E=85.5 MeV; 93Nb(16O, X), E=116 MeV; measured 4He, Li, Be, B, C fragment spectra, fragment σ, p and temperature parameters. Comparison with previous experimental σ data for Ag(3He, X) reaction at E=90, 198.6 MeV. Comparison with statistical models using CASCADE and GEMINI computer codes. Agreement for 4He fragment spectra, but not for higher Z fragments suggests using quantum mechanical perspective.
