ABSTRACT
A new method to tag the barium daughter in the double-beta decay of ^{136}Xe is reported. Using the technique of single molecule fluorescent imaging (SMFI), individual barium dication (Ba^{++}) resolution at a transparent scanning surface is demonstrated. A single-step photobleach confirms the single ion interpretation. Individual ions are localized with superresolution (â¼2 nm), and detected with a statistical significance of 12.9σ over backgrounds. This lays the foundation for a new and potentially background-free neutrinoless double-beta decay technology, based on SMFI coupled to high pressure xenon gas time projection chambers.
ABSTRACT
PIP: During the past 5 years, after a much longer period of studies and research, new methods of treatment for several gynecological disorders have been employed. Among such new methods the most important are: 1) the use of gonadotropin-releasing hormones as contraceptive agents, to diagnose cases of hypogonadism, or to cure amenorrhea. Gonadotropin-releasing hormones can be administered in several ways, provoke different reactions in different women, and are subject to several contraindications; 2) transphenoidal surgery for hypersecretory hypophysary tumors, or microsurgery of the hypophysis, which allows the identification of tumors smaller than 10mm, and which is used in the treatment of galactorrhea; 3) the use of ergot alkaloids derivates, such as bromocriptine or Lergotrile, to provoke menstruation and ovulation; 4) the clinical use of danazol in the treatment of endometriosis and in induction of ovulation; and 5) the treatment of primary dysmenorrhea by the use of synthetic inhibitors or by the use of prostaglandins.^ieng
