The prediction of single particle level crossing phenomenon between $2p_{3/2}$ and $1f_{5/2}$ orbitals in $Ni$- $Cu$-isotopic chains by the finite range simple effective interaction without requiring tensor part is discussed. In this case experimentally observed could be studied as a function nuclear matter incompressibility, $K(\rho_0)$. estimated for neutron number $N$=46 reproduced equation ...

‎Let $G$ be a finite non-abelian group with center $Z(G)$‎. ‎The non-commuting graph of $G$ is a simple undirected graph whose vertex set is $Gsetminus Z(G)$ and two vertices $x$ and $y$ are adjacent if and only if $xy ne yx$‎. ‎In this paper‎, we compute Laplacian energy of the non-commuting graphs of some classes of finite non-abelian groups‎..
