چکیده
We report experimental rate coefficients for the energy-pooling collisions K(4PJ)1K(4PJ)→K(4S) 1K(nl) with product states nl55P , 6S , and 4D . The experimental procedure and analysis are similar to those used in a recent study of energy-pooling collisions in cesium. In potassium, it was found that 4P1/2 14P1/2 collisions are more efficient than 4P3/214P3/2 collisions for populating 5P , while the opposite is true for populating 6S . Since fluorescence from 4D was not seen, we can only report an upper limit for that rate coefficient. @S1050-2947~97!08307-8#

متن کاملHUMAN AND CLINICAL NUTRITION Intake of polyphenol-rich pomegranate pure juice influences urinary glucocorticoids, blood pressure and homeostasis model assessment of insulin resistance in human volunteers
Pomegranate juice (PJ; also known as pomegreat pure juice) provides a rich and varied source of polyphenolic compounds that may offer cardioprotective, anti-atherogenic and antihypertensive effects. The aim of this study was to investigate the effect of PJ consumption on glucocorticoids levels, blood pressure (BP) and insulin resistance in volunteers at high CVD risk. Subjects (twelve males and...
