STATES IN THE MIRROR NUCLEI 16 N AND 16 F EXCITED BY THE 1 5 ~ ( p ' , r f ) REACTIONS
One of the important mechanisms in the (p,r) reaction is creating 2p-lh states with respect to the target. The reaction involves a large momentum transfer which leads to strong transitions with large orbital angular momentum transfer. In the A= 16 region one would expect to see transitions in which a p-shell hole is created and a pair of particles is inserted into the d512 shell. If the hole is...
متن کاملMicroscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives
The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...
متن کاملUltrafast Luminescence Decay in Rhenium(I) Complexes with Imidazo[4,5-f]-1,10-Phenanthroline Ligands: TDDFT Method
The interpretation of the ultrafast luminescence decay in [Re(Br(CO)3(N^N)] complexes as a new group of chromophoric imidazo[4,5-f]-1,10-phenanthroline ligands, including 1,2-dimethoxy benzene, tert-butyl benzene (L4) and 1,2,3-trimethoxy benzene, tert-butyl benzene (L6), was studied. Fac-[Re(Br(CO)3L4 and L6] with different aryl groups were calculated in singlet and triplet excited states. The...
متن کاملمحاسبه و بررسی سیستماتیکی پارامتر چگالی ترازهای هستهای
The knowledge of nuclear reaction rates is important for studying energy production and nucleosynthesis, especially in reactions including nuclei far from stability line, which are not accessible experimentally so far and thus it is necessary to be able to predict reaction cross sections in low excitation energies. Nuclear level density is one of the important key quantities in many nuclear phy...
متن کاملPopulation of Isomers in Decay of the Giant Dipole Resonance
The value of an isomeric ratio (IR) in N=81 isotones (137Ba, 139Ce, 141Nd and 143Sm) is studied by means of the (γ, n) reaction. This quantity measures a probability to populate the isomeric state in respect to the ground state population. In (γ, n) reactions, the giant dipole resonance (GDR) is excited and after its decay by a neutron emission, the nucleus has an excitation energy of a few MeV...
