“…To test the accuracy of the IQSO, six diatomic molecules are investigated. Model parameters of experimental constants of the diatomic molecules given in [36][37][38][39][40][41][42] are used to compute values of α, q, and V (r) via equations (7), (9), and (10) respectively. To enable comparison of results with existing potential in the literature, equations (2), (27), and (29) of [4], defining V (r), q, and α respectively, of the improved Tietz potential (ITP) are employed.…”

In this work, the improved q-deformed Scarf II oscillator (IQSO) is formulated through the Varshni conditions for diatomic molecule potential. Equation for bound state energy eigenvalues of the IQSO is obtained by the SUSYQM method, a Pekeris-like approximation scheme is used to model the centrifugal term of the Schrödinger equation. Expressions for molar entropy and Gibbs free energy are deduced for the IQSO from equations of energy eigenvalues and partition function within the context of Poisson summation formula. The IQSO is used to model experimental Rydberg-Klein-Rees (RKR) data of six diatomic molecules including: KRb (B 1Π), CO+ (X 2Σ+), Cl2 (X 1Σg +), ICl (X 1Σg +), NbO (X 1Σ+), and K2 (X 1Σg +). The average absolute deviation and mean absolute percentage deviation are used as accuracy indicators. Computed data revealed that the IQSO is an excellent model in fitting the RKR data of the diatomic molecules examined in this work. Numerical values of molar entropy and Gibbs free energy calculated for ICl (X 1Σg +) molecule are almost indistinguishable from existing experimental data for gaseous ICl (X 1Σg +) molecules. This suggests that the IQSO is a near perfect model for representing the internal vibrations of the ICl (X 1Σg +) molecule.

Molecular beams injected into the ISOLDE Radio-Frequency adrupole cooler and buncher (RFQcb), ISCOOL, have been studied under varying conditions using a new Time-of-Flight (ToF) detector. When a beam of molecules is injected into the RFQcb and interacts with the bu er gas, collisional dissociation processes may occur. In this study, two di erent beams of molecules, CO + and N + 2 , were separately injected into ISCOOL, and two di erent bu er gases (pure helium or a 90:10 mixture of helium and neon) were used. e radio-frequency of the RFQcb was varied as the molecules, along with the fragments from the dissociation processes, were extracted from ISCOOL and studied using the new Time-of-Flight detector. e main nding of this work is that the rates for molecular dissociation within ISCOOL were very small for both CO + and N + 2 , with the largest rates found for CO + .
