The methods to calculate the energy spectra of all kinds of emitting light particles and recoil nuclei for multilevel particle emission in medium energy region(≤250?MeV), comparison of the efficiency between this method and the traditional one and two calculated examples are given.

In the middle energy region,that is,12.5520≤E_t≤37.6560 kJ. mol~(-1),their reaction rates are almost the same because of the strengthen of the structural transformation and dissociation of the two complexes caused by the increase of energies.

The real parts of the optical potentials for n+40Ca and n +208Ph in the intermediate energy region are self-consistently calculated by utilizing Green function theory, nuclear matterapproximation and the semi-classical variation approach.

On the basis of the Skyrme interaction, the nuclear matter approach and the self-consistent semi-classical (SCSC) approach, the self-consistent study of microscopic optical potential (MOP) is generalized to the intermediate energy region (60-300MeV). The radial shape and the temperature effect of n + 90Zr optical potential are studied.

The differential cross sections and the spin observables of p-~(12)C elastic scattering in the whole intermediate energy region are calculated in the Glauber theory.

2)To drive R_(Cd) formula based on standard thermal average activation cross-section andresonance integral and to define all related parameters or factors including these in thermal energyregion and these in intermediate energy region.

A more accurate description of the intermediate energy region is also obtained.

The theoretical PDI total cross-section shows a relevant improvement in the intermediate energy region relative to the C3 model, which converges to data for photon energies larger than 1 keV.

The infrared and intermediate energy region (0.4GeV >amp;lt; p >amp;lt; 1.5GeV) is found to be most relevant for DCSB from analysis on the relation between the SD kernel and the quark mass function.

Furthermore, we present a comparison of perturbative QCD results (plus certain sum rules corrections) with non perturbative results from the lattice in the intermediate energy region.

Consequently, although it is suppressed by the factor , the twist-3 contribution is comparable with and even larger than the leading twist (twist-2) contribution at intermediate energy region of being .

The intermediate and fast neutron flux spectrum in the core of the swimming-pool reactor is measured by multiple foil activation method. There are 22 kinds of foil detectors chosen for the measurement, including 9 intermediate and 13 fast threshold foil detectors. They are irradiated ill the core position in cadmium box with 1 mm wall thick. Absolute foil activities from which reaction rate is determined are mainly measured by γ-spectrometer. The energy range from 0.28 eV to 18.5 MeV is divided into 470 energy...

The intermediate and fast neutron flux spectrum in the core of the swimming-pool reactor is measured by multiple foil activation method. There are 22 kinds of foil detectors chosen for the measurement, including 9 intermediate and 13 fast threshold foil detectors. They are irradiated ill the core position in cadmium box with 1 mm wall thick. Absolute foil activities from which reaction rate is determined are mainly measured by γ-spectrometer. The energy range from 0.28 eV to 18.5 MeV is divided into 470 energy groups. Neutron shielding factors of the foil are calculated for each group in intermediate energy range with detail consideration of cadmium filter and scattering by the foil itself. And from these factors effective neutron activation cross sections are obtained. The approximate neutron flux spectrum is calculated by the iteration method and spectrum errors are calculated by MonteCarlo method. From obtained spectrum one can evaluate spectrum average cross sections of each foil above 0.5 or 1 MeV for other applications. In this work flux spectrum process, evaluation of spectrum errors and activation determinations are described in detail. The specification of detector foils, reaction rates and its errors and calculated flux spectra are given. At last the convergence of iteration method and fluctuations of obtained spectra are discussed.

Furthermore, our calculations reflect shell effects clearly.

Projectile breakup in heavy ion reactions at the low side of the intermediate energy domain and incomplete deep inelastic collision, a reaction mechanism of dissipative process between target nucleus and the main part of the projectile after projectile breakup, are discussed in this paper. Some new experimental data on this subject in the energy region of 10-20MeV/u are given. The experimental results of the single and coincident measurements are interpreted in the framework of corresponding reaction mechanisms....
