Abstract

FIG. 2. Stereoscopic photograph of V° decay "B." Its apex is just below the horizontal bar across the picture, which is a sweeping field electrode suspended above the sensitive layer of the cloud chamber. The apex of the V° particle is vertically separated from the sweeping field electrode by about 5 cm in depth. The dashed line at the top of the picture points toward the part of the shield struck by the neutron beam. Information concerning the V° is given in Table I. C ALCULATIONS have been made 1 of the differential cross section for proton-proton scattering at 18.3 and 32 Mev. The pseudoscalar meson theory was analyzed and comparison was made with the 18.3-Mev data 2 and the 32-Mev data. 3 " -4

Interplay between Yukawa and Tomonaga in the Birth of Mesons

“…Such particles were believed to be neither the proton nor the electron (positron), presumably having a mass between that of the proton and the electron. In the same year, similar findings were reported by other groups [9,10,11]. Among them, two groups succeeded in determining the mass of such intermediate particles.…”

The theory of hypernuclei

“…Однако в случае Да-ниша и Пниовского трудно было сделать выбор между а) или с). Вскоре анало-гичный случай наблюдали Крюссар Морелле 2 . Они показали, что по крайней мере в их случае вариант а) не будет иметь места в силу энергетических соо-бражений.…”

Λ0-Fragment Decay in a Cloud Chamber

“…Many examples of bound A 0 decay have been found in nuclear emulsions. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] The fragments involved have charges from 1 to 9e, and they may decay with or without the emission of a IT meson. In two events, 7 -11 neither a IT meson nor an unattached nucleon was emitted.…”
