[en] A mechanism for neutron emission from deuterated metals is proposed, which is based on some known phenomena, concerning hydrogen precipitation in supersaturated metals. Transient electric fields are assumed to produce energetic deuterons and hence neutrons from D(d,n)³He reactions. The mechanism predicts neutron yields compatible with those reported in some of the experiments and implies a certain degree of experimental irreproducibility

[en] Li pellet conditioning in TFTR results in a reduction of the edge electron density which allows increased neutral beam penetration, central heating, and fueling. Consequently the temperature profiles became more peaked with higher central Ti, Te, and neutron emission rates.

[en] Neutron emission in fission is usually described in terms of two observables: the energy spectrum of emitted neutrons N(E) and the average number of neutrons emitted per fission, or average neutron multiplicity, /bar v/p. These observables are measured before the residual fission fragments decay toward the valley of β stability and are therefore referred to as the prompt neutron spectrum N(E) and the average prompt neutron multiplicity /bar v/p. They are of fundamental importance to the design of macroscopic systems that are driven by the fission reaction, such as thermal or fast reactors. It is the purpose of this paper to describe existing theoretical models for these two observables. Other observables for neutron emission in fission will not be described here due to space limitations. 12 refs., 2 figs

[en] Based on the model of micro hot fusion, the neutron emission rate of cold fusion is determined without the need for fine-tuning parameters. Moreover, the experimental conditions that are essential to reproduce fusion are determined. 84 refs

[en] The iterative EM algorithm is used to deconvolve neutron depth profiling spectra. Because of statistical noise in the data, artifacts in the estimated particle emission rate profile appear after too many iterations of the EM algorithm. To avoid artifacts, the EM algorithm is stopped using a cross-validation procedure. The data are split into two independent halves. The EM algorithm is applied to one half of the data to get an estimate of the emission rates. The algorithm is stopped when the conditional likelihood of the other half of the data passes through its maximum. The roles of the two halves of the data are then switched to get a second estimate of the emission rates. The two estimates are then averaged

[en] This paper describes the importance of microcosmic section measurement technique. The contents are differential cross section double-differential cross section and neutron emission cross section. It describes outline, set-up, method and system of cross section measurement. It can used for correlative work in future. (authors)
