The triaxiality of odd-mass nuclei is investigated by coupling a quasiparticle to an even-even core through the core-quasiparticle model. Both soft and rigid triaxial cores are considered. “soft core” described collective model with rotation-vibrational motion, while “rigid rotor model, which limiting case only rotational motion. We show that presence odd modifies quadrupole dynamics appear mor...

in this paper, natural frequencies of the sandwich plates with soft flexible core and composite face sheets are obtained. three-dimensional (3d) finite element method (fem) is used for constructing and analyzing of the sandwich plates to obtain their natural frequencies. continuity conditions for transverse shear stresses at the interfaces as well as transverse flexibility and transverse normal...

The internal energy of hard spheres (HS) is the same as that of an ideal gas, so that the energy route to thermodynamics becomes useless. This problem can be avoided by taking an interaction potential that reduces to the HS one in certain limits. In this paper the square-shoulder (SS) potential characterized by a hard-core diameter σ′, a soft-core diameter σ > σ′ and a shoulder height ǫ is cons...
