“…For the calculation of the most-probable alpha velocity we used empirical barrier energies from Figure 3 shows a mass-versus-energy spectrum for single events taken with one of the fission detectors. The spectrum has been corrected for pulse height defects [32], for plasma delays*, and for energy loss in the target [33]. The energy resolution for fission fragments was about 5 MeV; the mass resolution was about 7 ainu.…”

Energy and angular correlations between alpha particles and fission-like fragments in the reaction of asCI+Ag at 10MeV/n have been measured. The coincident yield is dominated by two mechanisms: sequential emission from both fragments (M~=0.137 _+0.014) and alpha emission from the composite system prior to scission (M,=0.124 _+0.012). The observation of nuclear shadowing for sequential emission from the fragments allowed us to estimate the "lifetime" of the 218 MeV excited 143Gd composite system as (1-3)x10-2~It is argued that this rather long time reflects the slow evolution in shape of the composite system and might be termed "sticking time," since statistical-model lifetimes are typically an order of magnitude shorter. Observed also are small contributions of nonequilibrium emission in the forward direction (M~=0.005 _+0.001) and a component displaying the characteristics of emission from the neck (M s = 0.010 + 0.002).

“…Therefore, the measured PH is no longer strictly proportional to the energy of the incoming heavy ion, but will also depend on its mass [37,38]. The PHD is attributable to physical processes occurring in the detector's material, one of the most important being the increased recombination of charge carriers for the heavier ions, as they produce a denser ionization track in the silicon detector [39,40].…”

The detailed analysis of the β-delayed fission data of 180 Tl is presented. The experiment was performed by producing a pure beam of 180 Tl by means of highly selective resonance laser ionization followed by mass separation with the ISOLDE (CERN, Geneva) isotope separator. A surprising asymmetric mass distribution of fission fragments from 180 Hg, the daughter of 180 Tl β decays, was observed. Here, the energy calibration of the silicon detectors, which is crucial for a proper determination of the fission fragments' energy and mass split, is presented and the total kinetic energy and its dependence on the mass split ratio is discussed. A more precise β-delayed fission probability P βDF ( 180 Tl) = 3.2(2) × 10 −3 % was deduced.

“…The PHD has been considered separately as, (1) energy loss in the entrance window, (2) energy loss by nuclear stopping and (3) energy loss caused by other effects. The theme researchers have been concerned is the third defect, called residual defect.…”

The residual defect in the pulse height defect of a silicon surface barrier detector is mvestigated theoretically. An application of the model of charge collection process leads to another candidate for the residual defect than the recombination defect. The residual defect is due to incomplete charge induction by electrons and holes inside a plasma column, which has dielectricity-like property. Quantity of induced charge is shown in a ratio to the number of produced electron-hole pairs as functions of depletion layer thickness, plasma column length and resistivity of the detector. Experimental result of the residual defect of 58 Ni ion and its analysis method applying this model are presented. The residual defect is successfully explained by this model.
