N. Bahcall & R. K. Ulrich in Astrophysical Jrnl. 160 l58 We have expressed the counting rate in solar-neutrino units: 1 SNU ≡ 10−36 capture per target atom per second. 1976 J. Kleczek Universe ii. 78 It is usual to specify the rate of the neutrino capture reactions..in terms of so-called solar neutrino units (SNU or ‘snew’) which are such that 1 SNU corresponds to 10−36 captures per target Cl atom per second. 1980 McGraw-Hill Yearbk. Sci. & Technol. 397/1 The low rate, if attributed to solar neutrinos, would correspond to a neutrino capture rate in the tank of 0·41 ± 0·07 per day. To compare this rate to [sic] the theory, one expresses the neutrino capture rate in solar neutrino units... The rate corresponds to 2·2 ± 0·4 SNU. < as lemmas |
