A K-meson is found to decay at rest into a nearly relativistic secondary particle. The secondary particle produces a nuclear disintegration in flight and is identified as a π-meson of kinetic energy ∼ 110 MeV. The event is interpreted as the decay

An attempt has been made to determine the abundance of low-energy tritons and deuterons in a nuclear emulsion stack exposed at a geomagnetic latitude, λ =61° N on August 3, 1958 under 3.8 g/cm2 of matter. The grain density versus range method has b

The maximum often observed at low energies in primary cosmic ray spectra is examined with respect to the possible effect of isotopic composition. It is shown that a maximum can arise if He/sup 3/ and He/sup 4/ are not distinguished and spectra are pl

The effect of ionization loss on a primary cosmic ray spectrum of the formN A, Z (e)=K(A, Z)γ/eγ+1 is calculated for1H,9Be,12C,19F,27Al,40Ca and56Fe as representative of the charge spectrum of primary cosmic rays. The calculation is carried out for

A study of nuclear disintegrations caused by α-particles of primary cosmic radiation with energies > 5 BeV per nucleon, has been carried out. In a systematic survey in nuclear emulsions using ‘along the track’ scanning method, 479 α-particles w

It is proposed that the characteristics of nuclear interactions of primary cosmic-ray nuclei (in-out interaction) be used to obtain the isotope abundance ratios for different charges. The applications of the procedure to singly and doubly charged nuc

The effect of spallation and ionization loss on the relative abundances and energy spectra of cosmic-ray nuclei of charge greater than two, during their propagation in the interstellar and interplanetary space, has been determined. Comparison of the

Nuclear interactions produced in nuclear emulsions by douterons of mean energy 275 MeV have been studied. The mean free path for douterons of this energy is found to be (16.6 ±1.8) cm.

The ratio R = He3/(He3 + He4) is determined using a nuclear emulsion stack exposed at the geomagnetic latitude 61°N on August 3, 1958, under 3.8 g/cm2 of matter. The ratio R found at the top of the atmosphere is 0.31±0.08 for the same energy per nu
