1970 J. 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.
1972 Ann. Rev. Astron. & Astrophysics 10 28 The best present estimates suggest..that the ultimate sensitivity of the current 105-gallon experiment will be set by the cosmic-ray background at ∼ 0·4 SNU.
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.
