Inelastic scattering of NO(AΣ) + CO: rotation-rotation pair-correlated differential cross sections.

A crossed beam velocity-map ion-imaging apparatus has been used to determine differential cross sections (DCSs) for the rotationally inelastic scattering of NO(AΣ, = 0, = 0.5) with CO, as a function of both NO(A, = 0, ') final state and the coincident final rotational energy of the CO. The DCSs are dominated by forward-peaked scattering for all ', with significant rotational excitation of CO, and a small backward scattered peak is also observed for all final '.

Differential Cross Sections for Pair-Correlated Rotational Energy Transfer in NO(AΣ) + N, CO, and O: Signatures of Quenching Dynamics.

A crossed molecular beam, velocity-map ion-imaging apparatus has been used to determine differential cross sections (DCSs), as a function of collider final internal energy, for rotationally inelastic scattering of NO(AΣ, = 0, = 0.5) with N, CO, and O, at average collision energies close to 800 cm. DCSs are strongly forward scattered for all three colliders for all observed NO(A) final rotational states, '.

Less Is More: A Narrative Review of Deciding When Surgical Intervention Should Be Withheld.

Decision-making in surgery is one of the great unspoken challenges, an important but markedly challenging skill that takes a lifetime to master. The choice not to operate generally proves a significantly harder conclusion than opting for intervention. Our paper explores the influences which affect a clinician's decision to operate or not.

Stereodynamics of rotational energy transfer in NO(Σ) + Kr collisions.

A crossed molecular beam, velocity-map ion imaging apparatus has been used to determine differential cross sections (DCSs) and angle-resolved rotational angular momentum alignment moments for the state-resolved rotationally inelastic scattering of NO(Σ, = 0, = 0.5 ) with Kr at an average collision energy of 785 cm. The experimental results are compared to close-coupled quantum scattering (QS) calculations performed on a literature potential energy surface (J.

Non-intuitive rotational reorientation in collisions of NO(A Σ) with Ne from direct measurement of a four-vector correlation.

Stereodynamic descriptions of molecular collisions concern the angular correlations that exist between vector properties of the motion of the participating species, including their velocities and rotational angular momenta. Measurements of vector correlations provide a unique view of the forces acting during collisions, and are a stringent test of electronic-structure calculations of molecular interactions. Here, we present direct measurement of the four-vector correlation between initial and final relative velocities and rotational angular momenta in a molecular collision.
