چکیده
We study structures of the $0^+$ states $^{13}_\Lambda$C within framework $\alpha+\alpha+\alpha+\Lambda$ four-body orthogonality condition model with Gaussian expansion method. obtain five and compare them low-lying four $^{12}$C. find that $0_1^+$, $0_2^+$ $0_4^+$ correspond to $^{12}$C, respectively. also both $0_3^+$ $0_5^+$ have analogous nature state where additional $\Lambda$ particle couples $^8$Be cluster one $\alpha$ cluster, in The former is then shown an elongated $^9_\Lambda$Be$(0_1^+) + \alpha$ structure a higher nodal behaviour for their relative wave function, latter dilute three-body gas consisting $2\alpha+^5_\Lambda$He clusters.

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
