High-spin isomer and the structure of the odd-odd nucleus
نویسنده
چکیده
It has been shown that the nuclear shell model depicts very well the structure of nuclei with mass A~208 (see [1] for example). This model describes the motion of nucleons outside an inert core (closed shells) that contains a magic number of protons and neutrons, more preferably both. In the region of interest here the doubly magic nucleus 208 Pb (Z=82, N=126) is initially taken as the core. The application of shell model calculations for nuclei with as many as eight quasiparticles outside the lead core, together with the search for high-spin isomeric states in the Fr isotopes, have motivated the present study.

Structure of isomeric states in 66 As and 67 As
Strong residual correlations between neutrons and protons in N ≈ Z systems can lead to unusual structure. Using the spherical shell model, we show that a low-excitation shape isomer can occur in the odd–odd N = Z nucleus 66As. This extends the picture of shape coexistence beyond even–even nuclei. Furthermore, it is demonstrated that in 66As and in the N = Z + 1 nucleus 67As, a new type of isome...
متن کاملSkolem Odd Difference Mean Graphs
In this paper we define a new labeling called skolem odd difference mean labeling and investigate skolem odd difference meanness of some standard graphs. Let G = (V,E) be a graph with p vertices and q edges. G is said be skolem odd difference mean if there exists a function f : V (G) → {0, 1, 2, 3, . . . , p + 3q − 3} satisfying f is 1−1 and the induced map f : E(G) → {1, 3, 5, . . . , 2q−1} de...
متن کاملSTUDY OF NUCLEAR LEVEL DENSITY AND SPIN CUT-OFF FACTORS
Nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹A‹63,from a microscopic theory, which includes nuclear pairing interaction. Single particle levels for both Seeger and Nilsson potentials were used in the calcdations. Level densities extracted from the theory are compared with their conesponding experimental values, It is found that the overall...
متن کاملFurther results on odd mean labeling of some subdivision graphs
Let G(V,E) be a graph with p vertices and q edges. A graph G is said to have an odd mean labeling if there exists a function f : V (G) → {0, 1, 2,...,2q - 1} satisfying f is 1 - 1 and the induced map f* : E(G) → {1, 3, 5,...,2q - 1} defined by f*(uv) = (f(u) + f(v))/2 if f(u) + f(v) is evenf*(uv) = (f(u) + f(v) + 1)/2 if f(u) + f(v) is odd is a bijection. A graph that admits an odd mean labelin...
متن کاملHigh spin proton emitters in odd-odd nuclei and shape changes
We present a formalism to describe proton emission from odd-odd nuclei based on a scattering like approach. Special emphasis is given to the case of transitions between states with different deformations. As an example we estimate the proton half-life of the odd-odd nucleus 58Cu. Our calculations show that the change of deformation in the decay process has a significant influence on the half-li...
