Non-nearest neighbour ICD in clusters

New Journal of Physics, 2016
Interatomic Coulombic decay (ICD) is an electronic decay process of excited, ionized systems. It has been shown to occur in a multitude of small and large systems. The effects of more than one possible decay partner are discussed in detail illustrated by

Critical Assessment of Theoretical Calculations of Atomic Structure and Transition Probabilities: An Experimenter’s View

Atoms, 2014
The interpretation of atomic observations by theory and the testing of computational predictions by experiment are interactive processes. It is necessary to gain experience with “the other side” before claims of achievement can be validated and judged ...

Lifetimes of singly charmed hadrons

Journal of High Energy Physics, 2022
We provide an extensive study of the lifetimes of singly charmed baryons and mesons, within the heavy quark expansion with all known corrections included.

CI-MBPT and Intensity-Based Lifetime Calculations for Th II

Atoms, 2020
Lifetime calculations of Th II J = 1.5 and 2.5 odd states are performed with configuration–interaction many-body perturbation theory (CI-MBPT). For many J = 2.5 states, lifetimes are quite accurate, but two pairs of J = 2.5 odd states and many groups of ...

Lifetimes of light stringy states

Nuclear Physics B, 2022
In this paper, we evaluate the lifetime of the light stringy states that emerge in intersecting D-brane realisations of the Standard Model. For concreteness, we focus on a light massive scalar decaying into two massless fermions.

Dust sputtering within the inner heliosphere: a modelling study [PDF]

Annales Geophysicae, 2020
The aim of this study is to investigate through modelling how sputtering by impacting solar wind ions influences the lifetime of dust particles in the inner heliosphere near the Sun.

On Uncertain Lifetimes [PDF]

Journal of Political Economy, 1977
This paper contrasts consumer choice under uncertain lifetimes with the behavior that would arise if each individual's lifetime were announced at birth. In a model that includes life insurance and excludes investments in human capital, the expected utility under uncertain lifetimes exceeds that under known lifetimes when the latter expectation is based

Limits to the Precision of Atomic Lifetime Measurements

Atoms
The mean lives of certain levels in atoms or not so highly charged ions have been measured with a precision on the order of 0.1%. This is better than most other atomic lifetime measurements, but is still much less precise than many measurements of other ...

Charge-Swapping Q-balls and Their Lifetimes

Journal of High Energy Physics, 2021
For scalar theories accommodating spherically symmetric Q-balls, there are also towers of quasi-stable composite Q-balls, called charge swapping Q-balls (CSQs).

Improved limit on the directly measured antiproton lifetime

New Journal of Physics, 2017
Continuous monitoring of a cloud of antiprotons stored in a Penning trap for 405 days enables us to set an improved limit on the directly measured antiproton lifetime.
