Abstract
On the occasion of the 70th birthday of Edoardo Amaldi, about two years ago, I was invited to give a review talk on Neutrino Physics at the International Assembly of physicists, the major part of which was certainly not composed of neutrino physicists. Then the talk was much simpler than today, since you are all professional “neutrinists”. Notice that I have only 30 minutes at my disposition (instead of 2 hours at the Amaldi Conference). I must avoid the danger of being trivial by telling you the a,b,c of your work. A way out of this difficulty, maybe, is to give a few recollections of such developments in neutrino physics which either are curious and at the same time very important (Pauli, Fermi) or about which I happen to be well informed for various reasons. Thus my talk will be entirely subjective (at a variance with the one I gave at the Amaldi celebration) and will be mainly dedicated to the young gene ration of neutrino investigators, who are well informed about today and yesterday developments, but not so well about old ones. I shall not talk about today problems, of course, since you are all here to discuss them during almost a week. By the way, most of you are used to thinking in terms of 105 – 106 neutrino events and forgot, if you knew it, that 16 years after the Pauli neutrino hypothesis (1930) neutrinos were still considered as undetectable particles, and, as you heard today, they were first revealed in the free state only 25 years after they had been invented.

Pauli: letter (4 December 1930) to a meeting of physicists, among which Geiger and Meitner, taking place in Tübingen. The letter was conserved by Meitner and its content was discussed since 1930. The letter was widely published only after many years. (See, for example: Brown, Phys. Today, September, 1978).

For accurate measurements in the reaction 37A+e− →37Cl+ν (K-capture) see: Rodeback, Allen, Phys. Rev., 86: 466 (1952). A striking picture of apparent non-conservation of momentum in the beta decay of He into Li and an electron by Csikay and Szaley appeared in Proc. of the Intern. Conf., Paris, Publ. Dunad (1959).
See for reviews of the subject: Primakov and Rosen, Report on Progress in Physics, 22: 121 (1959); Fiorini, Proc. of the ν’77 Conf., Ed. Nauka, Moscow (1978). Neutrino-less double beta decay has not been observed and upper limits 10−3 − 10−4 for the lepton non-conserving relative amplitudes have been set for the double decays 48Ca→48Ti (Bardin et al.), 76Ge→76Se (Fiorini et al.), 82Se→82Kr (Cleveland et al.), 103Te→103Xe (Zdelenko et al.).
The first measurements of the 3H beta spectrum were performed by means of proportional counters in 1949: Hanna, Pontecorvo, Phys. Rev., 75: 983 (1949)
Curran et al., Phil. Mag., 40: 53 (1949). Then substantial improvements were obtained by using as a 3H source a few molecule thick layer and a magnetic spectrometer, by Bergkvist, CERN Report 69-7: 91 (1969)
Curran et al., Nucl. Phys. B39: 317 (1972). The last and best result is mνe ⩽ 35 eV (90% C. l.) (Tret’jakov et al., Proc. of the Int. Conf. on High Energy Phys., Tbilisi, Vol. II: 118 (1976)). Less accurate measurements have been performed by implanting 3H in a Si(Li) detector (Simpson, Proc. ν’79 Conf., Vol. 2: 208).

These experiments gave upper limits as bad as \( {\text{R}}\,{\text{ = }}\frac{{\mu \to e\gamma }} {{\mu \to all}}\, \leq 10\% . \) Values of R were greatly improved in a number of experiments, the bsst of which, performed with a gamma hodoscope and a magnetic spectrometer, gives a limit as good as R→2·10−10 at the 90% c. l. (Anderson, Hofstadter et al., Proc. of the Tokyo International Conference, (1978)). For other similar processes the following limits are obtained \( {{R'}}\,{\text{ = }}\frac{{\mu \to 3e}} {{\mu \to all}}\, \leq 2.10^{ - 9} \) (Korenchenko et al., Proc. of the ν’77 Conference) and \( {{R'' = }}\frac{{\mu ^{\text{ - }} + ^{32} {\text{S}} \to {\text{e}}^{\text{ - }} + ^{32} {\text{S}}}} {{\mu ^{\text{ - }} + ^{32} {\text{S}} \to \nu _\mu + \ldots }} \leq 1.5 \cdot 10^{ - 10} \) (Badertscher et al., Phys.
