On the mechanism of nonradiative decay of DNA bases: ab initio and TDDFT results for the excited states of 9H-adenine Minimum-energy reaction paths and corresponding potential-energy profiles have been computed for the lowest excited states of the amino form of 9H-adenine... AL Sobolewski,W...
The decay of Tlsources was investigated by means of scintillation and semiconductor spectrometers. β-γ, γ-γ, and γ-sum-coincidence measurements were carried out. The β spectrum (from shell-model considerations presumably a first-forbidden transition) was decomposed into three components of 2.34...
Using these relations, we shall study strong decay properties of states as molecular states. Our strategy is quite straightforward. First we need a hidden-charm pentaquark current, such as (2) where a \cdots e are color indices. It is the current best coupling to the \bar{D}^0 \var...
The analysis of the local uniqueness and a result similar to Corollary 1.1 in the interval 1+\frac{2}{n}<p<2 is also important. However, we prefer to concentrate on the case p>2 since our proofs use essentially the exponential decay of the ground state. In the case 1+\frac{2}{n}...
Bound states in the continuum (BICs) have attracted attention in photonics owing to their interesting properties. For example, BICs can effectively confine light in a counterintuitive way, and the far-field radiation of photonic structures that exhibit B
The lifetime of the spin 10 SD state is reduced as compared to the rotational value due to the γ decay out of the band. This decay can be described by a very small admixture of normal deformed states to the spin 10D state. The obtained lifetimes provide strong experimental evidence for ...
We also present upper limits for the decays of χinto these final states. These results give information on the decay mechanism of χstates into pseudoscalars. 关键词: 13.25.Gv DOI: 10.1103/PhysRevD.75.071101 被引量: 12 年份: 2007 收藏 引用 批量引用 报错 分享 ...
The time-dependent current density curves recorded for 2 h at various potentials illustrate its superior durability (Fig. S22), and there was almost negligible decay in the current density at − 0.6 V (vs. RHE) after 18 h chronoamperometry test (Fig. S23). Notably, the urea yield ...
Σc(∗)Σc(∗). Taking into account heavy quark spin symmetry breaking, we predict several bound states of isospin I=0, I=1, and I=2 in the one boson exchange model. Moreover, we adopt the effective Lagrangian approach to estimate the decay widths of ...
Because of the stronger ion-lattice coupling, nonradiative decay rates for transitions involving 5d states are much faster than those between 4f states. Decay rates are dependent upon the temperature and the energy gap to the next-lower level. The temperature dependences of the 5d fluorescence ...
