CHORUS is an experiment searching for ! oscillation in the CERN wide band neutrino beam with a hybrid setup consisting of a nuclear emulsion target followed by electronic detectors. The experiment has been taking data from 1994 through 1997. A subset of the neutrino interactions collected in 1994 and 1995 have been analyzed, looking for charged current(More)
The r-process is supposed to be a primary process which assembles heavy nuclei from a photo-dissociated nucleon gas. Hence, the reaction flow through light elements can be important as a constraint on the conditions for the r-process. We have studied the impact of di-neutron capture and the neutron-capture of light (Z10) elements on r-process(More)

On leave of absence from ITEP, Moscow. Abstract We report on a search for associated charm production in neutrino charged-current interactions in the CHORUS experiment, based on the visual observation of charmed-particle decays. The search differs from those carried out so far in which the production of ') (' has been inferred from measurements of events(More)
A new experimental approach to the famous problem of the anomalously slow Gamow-Teller (GT) transitions in the beta decay of the A=14 multiplet is presented. The GT strength distributions to excited states in 14C and 14O were studied in high-resolution (d,2He) and (3He,t) charge-exchange reactions on 14N. No-core shell-model calculations capable of(More)

In an experiment designed to overcome the loopholes of observer dependent reality and satisfying the counterfactuality condition, we measured polarization correlations of 1 S 0 proton pairs produced in 12 C(d, 2 He) and 1 H(d, 2 He) reactions in one setting. The results of these measurements are used to test the Bell and Wigner inequalties against the(More)
