Abstract
A signal of theΦ-K+K− decays has been observed in neutron-hydrogen interactions at energies of 30–70 GeV in an experiment using the BIS-2 spectrometer. The longitudinal momentum spectrum in the forward region,x F<0·1 atp T<1 GeV/c, can be well described by a power law dependence (1−x F)N withN=4·28±0·42. Thep 2T -spectrum has been parametrized by the exp(−Bp 2T ) law with the exponentB=(3·02±0·55) (GeV/c)−2. The extrapolation of the measured cross section to the full kinematic region yields a value of (220±85) Μb in agreement with measurements from the proton beams.
