“…[26]. The spin-parity has been determined using proton transfer studies and γγ angular correlation measurements, which support an assignment of J π = 1/2 − [10,32]. Since our incident proton beam is unpolarized, conservation of angular momentum dictates that the primary transition γ-rays are emitted isotropically.…”

Silicon synthesis in high-temperature hydrogen burning environments presents one possible avenue for the study of abundance anomalies in globular clusters. This was suggested in a previous study, which found that the large uncertainties associated with the 30 Si(p,γ) 31 P reaction rate preclude a firm understanding of the stellar conditions that give rise to the Mg-K anti-correlation observed in the globular cluster NGC 2419. In an effort to improve the reaction rate, we present new strength measurements of the E lab r = 435 keV and E lab r = 501 keV resonances in 30 Si(p,γ) 31 P. For the former, which was previously unobserved, we obtain a resonance strength of ωγ = (1.28 ± 0.25) ×10 −4 eV. For the latter, we obtain a value of ωγ = (1.88 ± 0.14) ×10 −1 eV, which has a smaller uncertainty compared to previously measured strengths. Based on these results, the thermonuclear reaction rate has been re-evaluated. The impact of the new measurements is to lower the reaction rate by a factor of ≈10 at temperatures important to the study of NGC 2419. The rate uncertainty at these temperatures has also been reduced significantly.Usage: Secondary publications and information retrieval purposes.

This article reviews Binary Tense theory as developed by Verkuyl (2008) on the basis of three oppositions proposed by Te Winkel (1866): present-past, synchronous-posterior and imperfect-perfect. Verkuyl followed Te Winkel in assuming that the verb zullen ('will') can be used as a temporal auxiliary expressing posteriority, but here it will be argued that zullen should be considered a purely modal verb and thus does not contribute to the temporal meaning of the clause. The notion of posteriority is, in fact, an integral part of the meaning of past and present, and can be brought to the fore by the use of temporal adverbs like morgen 'tomorrow' or by pragmatic considerations. The article discusses several proposals in the Dutch linguistic literature in which the modal nature of zullen is recognized, but they fail to be convincing in the absence of a crucial innovation: the rejection of the point of speech n as the present in favor of assuming a present tense domain in which n is a moving point that splits the actualized part of the present from its non-actualized (modal) part. • 1 Introductie Voorzover ons bekend, is L.A. te Winkel (1810-1868) de eerste geweest die voorstelde om het Nederlandse tempussysteem te beschrijven in termen van drie binaire opposities: (1) a. Heden (PRES) vs. Verleden (PAST) b. Synchroon (SYN) vs. Posterieur (POST) c. Imperfect (IMP) vs. Perfect (PERF) Te Winkel (1866) hanteert niet de primaire driedeling Verleden-Heden-Toekomst die gebruikelijk is geworden in de taaltheoretische en logisch-semantische traditie gebaseerd op Reichenbach (1947) en die in zijn tijd ook al bestond in gebruiksgrammatica's en in * Henk Verkuyl is als emeritus hoogleraar verbonden aan de Universiteit Utrecht (email: H.J.Verkuyl@uu.nl). Hans Broekhuis is als onderzoeker verbonden aan het Meertens instituut te Amsterdam (hans.broekhuis@ meertens.knaw.nl). We willen de gastredactie en de beoordelaars van dit artikel bedanken voor hun commentaar dat ons in staat heeft gesteld onze presentatie op verschillende punten te verhelderen. Temporaliteit en modaliteit 307 de taalkundige vakliteratuur: Weiland (1805), Bilderdijk (1826), Kollewijn (1892), Den Hertog (1903), om maar enkele Nederlandse driedelers te noemen. Te Winkels keuze voor een binair systeem was toen ook al opvallend. De driedeling sluit als vanzelfsprekend aan op onze intuïties over hoe tijd zich het best laat ordenen op basis van onze dagelijkse ervaringen ermee: we praten over dingen uit het verleden, in het heden en in de toekomst. Desondanks stelt Te Winkel dat de voornaamste indeling van de Nederlandse tempusvor-men die is tussen Heden en Verleden, waarmee de rol van het Futurum als tempusvorm secundair wordt. Verkuyl (2012) is een korte samenvatting van Te Winkels systeem zoals dat formeel-semantisch gemoderniseerd is in Verkuyl (2008). In deze formalisering worden elementen die systematisch bijdragen aan het tempussysteem uitgedrukt door de operatoren die in (1) per oppositie staan vermeld. Voor elk van de zes operatoren geldt dat hij staat vóór ee...
