Sawyer, B. C., Stuhl, B. K., Yeo, M., Tscherbul, T. V., Hummon, M. T., Xia, Y., et al. Cold heteromolecular dipolar collisions.
Abstract: We present the first experimental observation of cold collisions between two different species of neutral polar molecules, each prepared in a single internal quantum state. Combining for the first time the techniques of Stark deceleration, magnetic trapping, and cryogenic buffer gas cooling allows the enhancement of molecular interaction time by 10$^5$. This has enabled an absolute measurement of the total trap loss cross sections between OH and ND$_3$ at a mean collision energy of 3.6 cm$^{-1}$ (5 K). Due to the dipolar interaction, the total cross section increases upon application of an external polarizing electric field. Cross sections computed from \emph{ab initio} potential energy surfaces are in excellent agreement with the measured value at zero external electric field. The theory presented here represents the first such analysis of collisions between a $^2\Pi$ radical and a closed-shell polyatomic molecule.

Abstract: This study integrates and applies theoretical models linking parent cognitions to maternal engagement in a parenting program to prevent child aggression and conduct problems. African American and European American mothers of preschoolers (N = 347) reported on their child's behavior, family demographics, and parental cognitions (i.e., parenting efficacy, child attributions, perceived benefits and obstacles to engaging in a parenting program). Parental cognitions predicted mothers' intent to enroll, actual enrollment, and attendance in a preventive parenting program after controlling for demographic and child factors. Parenting efficacy, perceived benefits, and obstacles to engagement made unique contributions in predicting engagement.
