ISOTOPIC-SPIN IMPURITY IN THE ALPHA-PARTICLE YALCIN, C; ASHGARIS, M; KORU, H (Springer Science and Business Media LLC, 1992-05-01) The isotopic-spin impurity introduced to the ground state of an alpha-particle by the Coulomb plus specifically charge-dependent nuclear forces is investigated. The upper limit of the impurity is calculated by shell model wave functions. The sum of the squared amplitudes of T=1, L not-equal 0 states is found to be in the order of 10(-4), which is one order of magnitude greater than earlier predictions.

Alkyl end group Modification of Benzotriazole and Thiophene Containing Conjugated Polymers Cevher, Şevki Can; Keleş, Duygu; Özdemir Hacıoğlu, Şerife; Toppare, Levent Kamil; Çırpan, Ali (null; 2016-07-21) This study focused on modifying the alkyl‐end‐group of benzotriazole and thiophene containing conjugated polymers. Introducing a moiety with struc‐turally rigid and tendency to enhance the π‐π stacking and also absorption in the high energetic region, influence the both electronic and optic properties of the conjugated polymers. Stille cross coupling chemical polymerization method was performed to synthesize the polymer contains: benzotriazole and bisthiophene. Characterizations of polymers were done in ter...
The ground state spin ordering and lowest energy excitations of a model organic ferrimagnet-polyallyl spin chain Cheranovskii, VO; Özkan, İlker (2001-01-01) We studied zero-temperature magnetic ordering in a model organic ferrimagnet-polyallyl spin-1/2 chain as a function of the exchange integral lambda describing the interaction between spins of radical centers and the main chain. Exact diagonalization and density matrix renormalization group (DMRG) methods demonstrated that for small applied fields, the difference in zero-temperature magnetizations of the sublattices reaches a maximum value at lambda = 0.70. It was shown that there is a critical value of magn...
