Cluster decays of 12Be excited states

Frontiers in Physics, 2022
An experimental study of the helium-cluster decays of the 12Be excited states has been performed using the 9Li + 7Li → α + α + 8He and 9Li + 7Li → α + 6He + 6He reactions at the 9Li beam energy of 74.8 MeV.

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.

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.

Radial excitations of the decuplet baryons

European Physical Journal C: Particles and Fields, 2017
The ground and first excited states of the decuplet baryons are studied using the two-point QCD sum rule approach. The mass and residue of these states are computed and compared with the existing experimental data and other theoretical predictions.

Primordial gravitational waves from excited states

Journal of High Energy Physics, 2022
We show that a scalar excited state with large occupation numbers during inflation leads to an enhancement of tensor modes and a characteristic pattern of order-one oscillations in the associated stochastic gravitational wave background (SGWB) sourced ...

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 ...

Theoretical Determination of Rate Constants from Excited-States: Application to Benzophenone [PDF]

, 2021
A cost-effective method of theoretically predicting electronic transition rate constants from the excited-states of molecules is reported. This method is based on density functional theory calculations of electronic states and quantitative rate constant ...
