A new three dimensional constrained method to reconstruct the charged particle tracks for the forward spectrometers is introduced.Using the method of least squares to solve the eqution,the parameters of the tracks can be obtained.In order to reduce t...

Abstract:
The cocycle condition of the action in the Liouville theory has been proposed.Several composition laws could be deduced from the cocycle condition,such as the composition law of the action in 2-D induced gravity in light-cone gauge,and that of the ge...

Under the Hartree mean-field approximaion and the high-temperature approximation,we established the mapping relation between some types of the special solutions of the φ4 model and the nontopological soliton bag model.From the mapping relation we see...

Abstract:
Boudjema et al.have found a very good method to identify the theoretical origin of an extra z boson.The method can separate different models.We calculate the z02 decay width of SU(60 model by using their method and compared with E6.

Abstract:
The excitation functions are determined by activation method and stacked-foil technique for the reactions Mo(d,x)95mTc,Mo(d,x)96gTc and Mo(d,x)97mTc from 3.2 to 13.5MeV.The experimental results are compared with theoretical calculation by compound nu...

Cross sections and recoil properties were measured for target residues from the interaction of 181Ta with 45MeV/A 12C ions using thick target-thick catcher foil techniques.The mass yield distribution measured experimentally was compared with a statis...

Abstract:
The deformation parameters of the first excited 2+1 states in 58,60,62,64Ni are obtained by comparing the experimental inelastic (p,p′) differential cross-section with the prediction of zero range DWBA.IBA is used to study the energy spectrum and B(E...
