Excited-State Absorption in Silver Nanoclusters

, 2021
To understand the decay mechanisms of plasmon resonances, we study the excited-state dynamics in atomistic silver clustersAg102+ (Td), Ag135+ (Ih), Ag131– (Oh), Ag191+ (D5h), Ag20 (Td), and Ag553– (Ih)using real-time time-dependent density functional ...

Electronically Excited States of Free Radicals

Physchem, 2023
Formation of the excited doublet (D) and quartet (Q) states of free radicals under their photoexcitation is discussed. The relative positions of the D and Q states are compared to the positions of the photoexcited states of organic molecules (Jablonsky ...

Spectroscopy at the two-proton drip line: Excited states in 158W

Physics Letters B, 2017
Excited states have been identified in the heaviest known even-Z N=84 isotone 158W, which lies in a region of one-proton emitters and the two-proton drip line.

Resonances in Systems Involving Positrons

Atoms, 2020
When an incident particle on a target gets attached to the target, the cross-section at that energy could be much larger compared to those at other energies. This is a short-lived state and decays by emitting an electron.

Excited States of Maximal Warm Holes

Universe, 2023
Recently, the Einstein–Maxwell–scalar model with a non-minimal coupling between the scalar and Maxwell fields was explored. As a result, a new class of black hole solutions with scalar hair was discovered.

Influence of energy gap between charge-transfer and locally excited states on organic long persistence luminescence

Nature Communications, 2020
Organic long-persistent luminescence (LPL) is an organic luminescence system that slowly releases stored exciton energy as light. Organic LPL materials have several advantages over inorganic LPL materials in terms of functionality, flexibility ...

Exchange Spin Coupling in Optically Excited States

, 2022
In optically excited states in molecules and materials, coupling between local electron spins plays an important role for their photoemission properties and is interesting for potential applications in quantum information processing.

Nucleon pairing in Sn isotopes

EPJ Web of Conferences, 2016
The systematics of excited states in Sn isotopes are discussed on basis of pairing interaction in nuclei. Nucleon paring leads to formation of excited states multiplets.
