✦ Synopsis
With thc graclu:il accumulation of experimental data in the solar ncutrino experimcnt of DAVIS and collaborators (runs 18 -74 for 1970r g R ~) , the question, whttthcr there arc time variations of the solar neutrino flux, is of rcnewcd intcrcst. \Vc discuss tlic matliematical-numerical methods applied to t h e statistical analysis of I)AVIS' argon-37 production rate up till now known in the litrraturc. Thcsc methods arc characterized by the arbitrary arrangcnicnt of the DAVIS d a t a i n a time scrics. We perform a crrtain Fourier transformation for uncqually-spaccti timc scrics of tlie mcasuring data of the argoti-37 production rate, discuss tlw tliscoverd prriotls and givc significance criteria with rcspcct to each period. V'c find t h a t all periods tlisciisscd in the literature arc containctl i n our wries of periods. Pointing out thc niorc mathematical character of the time serics analysis we emphasize tlic l)rctloniinant si::nificancc, of the detcctcd periods. &fit der wacliscndcn Zahl an McDcrgebnissen im solnrcn Seutrinocxpcrimont von DAVIS und Mitarbcitcrn (Expcrimcnte IS-74 im Zeitrauni 1970 1982) steht wcitcrhin die Fragc, ob dcr solare Ncutrinostroin zcitlichcn Schwankungen unterworfcn ist.
